How to Choose an Apple Watch


Updated January 13, 2022

When you buy an Apple Watch, you can be sure of precise workmanship, a wealth of health features and perfect iPhone compatibility. Apple Watches can measure your heart rhythm (ECG), heart rate, ambient noise and automatically call for help should you fall over or come off your bike. They can show notifications, incoming messages and deal with calls. The latest Apple Watch Series 7 shows the information on a display that never goes to sleep. Apple watches run on watchOS and have over 10,000 apps for you to download from the App Store. They are available in 45mm and 41mm variants.

Tips for Choosing an Apple Watch

  1. Even older Apple Watches offer plenty of features, such as displaying notifications and receiving calls on your iPhone. With each new generation, something is added. For example, you can take an ECG test on watches from Series 4 and upwards.
  2. You can choose from a range of colours and different case materials.
  3. The newest Apple Watches are available in 41 and 45mm. The smaller strap is normally more suitable for women, the larger size for men.
  4. The straps are all interchangeable between series, so you can use a Series 1 strap for a Series 5 watch. Note, however, that the sizes must match.

Important Apple Watch Parameters


  • Aluminium

Apple Watches from Series 1 to Series 5 are offered with aluminium cases. Although aluminium does not look as luxurious as stainless steel, it is light and relatively durable. Aluminium Apple Watches are cheaper than models made from other materials. It is also the only version that can be purchased on the current Czech market. Aluminium Apple Watches are available in space grey, silver and gold.

  • Stainless steel

Steel is heavier than aluminium, but you won't notice any weight difference on your wrist. It is a very strong and durable metal and adds a touch of luxury. That's why Apple uses stainless steel on the iPhone 13 Pro and iPhone 13 Pro Max. Apple Watches with stainless-steel cases are more expensive than aluminium ones but are not currently available on the Czech market.

  • Ceramic

The Apple Watch Edition Series 5 and newer boast a ceramic version. Ceramic is lighter than steel, highly durable and looks amazing. However, it is much more expensive than the base-price aluminium Apple Watch and, once again, is not available on the Czech market.

  • Titanium

For the first time, the Apple Watch Series 5 introduced a titanium version, which is even lighter than ceramic and significantly lighter than steel. Would you like to buy one? Sorry, we can't help as the Titanium Apple Watch is not available on the Czech market. If it was, it would cost considerably more than an aluminium Apple watch.


Apple has made every effort to make connectivity between your Apple Watch and iPhone simple and reliable. You don't have to worry about a complicated setup. However, every Apple watch is not compatible with every iPhone. For example, Apple Watch Series 6 requires an iPhone 6s or later that is running on iOS 14 or later.

Functions and Applications

Apple Watch has a rule that each generation of watches adds new features while retaining old ones. In other words, every version can do what its predecessor could plus something extra. So, what did each new version bring? The list of functions is summarised below.

Apple Watch Series 1

  • View notifications from your iPhone - Never miss an important announcement again.
  • Play music - You can easily play music from iTunes, including during your workouts.
  • Heart Rate Sensor - Gives you information about your activities.
  • watchOS 4 - The latest operating system lets you download thousands of applications.

Apple Watch Series 2 adds the following features

  • Built-in GPS navigation - You can record your route without taking your iPhone.
  • Waterproof 50M (5 ATM) - The watch can handle depths up to 50m.
  • Enhanced Activity Tracking - Now you can analyse your activities after recording them and your watch will remind you to move if you are inactive for a long time.

Apple Watch Series 3 adds the following features

  • Make calls - With eSIM, you can make calls or send SMS messages and leave your iPhone at home or on your desk.
  • Advanced Sports Mode - Provide you with a personal trainer and detailed activity analysis.
  • Apple Music and Siri - You can now enjoy these services without pairing the watch with your iPhone.
  • Wireless charging - You can now charge your watch wirelessly using the AirPower pad.

Apple Watch Series 4 adds the following features

  • Larger Display - The Apple Watch Series 4 display is approximately 30% larger. Even the smaller version has a bigger display than the larger watch from the previous generation. However, the watch itself is only slightly larger and 7mm thinner than the Series 3.
  • Fall Detection - Apple Watch 4 can detect a hard fall and display an alert. Then you can either contact emergency services or dismiss the alert by confirming that you are OK.
  • Haptic Crown Feedback - the digital crown is smaller on Apple Watch 4 than before, but now offers a haptic response. As it rotates, you can feel a slight knock.
  • Walkie-Talkie - Apple Watch 4 has a Walkie-Talkie feature and a speaker that is 50% louder.
  • Bluetooth 5.0 Support - The latest version of Bluetooth has a wider range and more reliable connectivity with iPhones.
  • Ceramic Back - Apple Watch Series 3 and earlier had a back of either ceramic or composite glass. AW Series 4 uses only ceramics.

Apple Watch Series 5 adds the following features

  • Always-On - With the Always-On display, Apple Watch Series 5 never sleeps. This means you can always see the time and watch face without even raising your wrist. This is useful in many situations, for example, if you want to check the time discreetly during a meeting. If you do not want to use this feature, you can easily turn it off.
  • Compass - A compass may seem to be unnecessary in this day and age but if you want to use one, now you can.
  • Emergency SOS - An international feature that calls the local emergency number for you. This feature is only available for cellular models, which are not available on the Czech market.
  • New materials - Apple Watch Series 5 is made not only from aluminium and steel but also from ceramics and titanium. Aluminium is the cheapest but other materials look more luxurious. Unfortunately, in the Czech Republic, only the aluminium version is for sale.
  • New watch faces - Apple adds new watch faces that are only accessible on Apple Watch Series 5 and later.

Apple Watch Series 6 adds the following features

  • Oxygen saturation – Apple Watch Series 6 boasts a revolutionary sensor and app to measure your blood oxygenation levels. This is a key indicator of overall fitness.
  • ECG – The ECG app on Apple Watch Series 6 can generate an electrocardiogram similar to a single-lead ECG. For such a small device, this is something extraordinary. It will provide important data for doctors and peace of mind for users.
  • Always-On Retina Display – The display never goes off, so you can keep track of the time and everything important. It goes all the way to the edges and is 30% larger than the Apple Watch Series 3 display.
  • S6 chip – Apple Watch Series 6 features the new Apple S6 chip, which includes a 64-bit dual-core processor that's up to 20% more powerful than the older S5 chip.
  • New watch faces – Apple adds more watch faces as new versions of watchOS arrive, but some will only be available on Apple Watch 6.

How is the Apple Watch SE different from the Watch Series 6?

  • Missing health features – Thanks to the noticeably lower price, it's clear that Apple Watch SE lacks the novelty features of blood oxygenation measurement and wrist ECG functionality. However, both heart rate and fall detection are available.
  • No Always-On – Another important concession is the lack of an always-on display.

Apple Watch Series 7 adds the following features

  • Larger display – The new generation of Apple Watch Series 7 features a display that extends all the way to the edges. The complete redesign of the display has reduced the bezel by 40%, so the screen area is now almost 20% larger than on Series 6. And more than 50% larger than the Series 3.
  • Five brand-new colours – Series 7 also comes in new colour options. Specifically, you can look forward to these: blue, midnight, starlight, green and (PRODUCT) RED. These colours will be available in an aluminium version.
  • Brighter display – The improved display backlight is 70% brighter in always-on mode.
  • Increased durability – Dramatic design changes have resulted in the strongest front glass ever. This makes it much harder to scratch the Apple Watch Series 7 display.
  • Faster charging – While the watch's battery life hasn't increased, Apple has worked on faster charging. With updated charging architecture and a fast-charging USB-C cable, you can take your battery from zero to 80% in just 45 minutes.

If the basic apps are not enough for you, there is nothing easier than downloading more from the App Store where you can find more than 10,000 apps including social networks, navigation, weather and games.

The watch also supports Apple HomeKit, so you can control your smart home with your watch.


Apple Watch is available in a variety of sizes.

The dimensions of each option are specified by the diameter of the dial, the dimensions of the AMOLED Retina display and the width of the strap.

Apple Watch Series 7:

  • 41mm
  • 45mm

Apple Watch Series 6, 5 & 4:

  • 40mm - This watch with a narrower strap is lighter and more comfortable for ladies to wear. The display has a 394×324p resolution.
  • 44mm - This option is slightly heavier and has a wider strap. The screen has a 448x368p resolution and is generally preferred by men. The larger display makes information easier to read.

Apple Watch Series 3, 2, and 1 are/were sold in smaller sizes:

  • 38mm - 340×272p display.
  • 42mm - 390×312p display.


Apple has never been afraid to put a bold price on its products and this is also the case with Apple Watch. The base version of the Apple Watch Series 6 costs almost 10,000 CZK. However, there are many smartwatches on the market, especially sports watches, which are much more expensive than Apple watches. Apple Watch's philosophy is clear. It offers top-quality design, perfect readability and exemplary compatibility with the iPhone and other Apple products. If you want a watch that works superbly in every situation, the price of an Apple Watch may seem reasonable. You can count on Apple reducing the price of previous generations with the advent of each new series.

Customisation is Possible

There is a wide range of customisation options for all Apple Watches, so you can have great fun personalising your watch. You can adjust your style by keeping several straps and changing them to suit the occasion. You can also choose recharging stands, power banks and more from our range of Apple Watch accessories.

  • Interchangeable straps - You can choose straps with different colours and a range of materials including nylon, leather, fluoroelastomer or high-grade stainless steel loop or link bands. The selection includes original Apple straps and those designed by independent manufacturers.
  • Charging Stands - Get a docking station to easily charge your Apple Watch. They are produced by several manufacturers who offer a range of different shapes and materials.
  • Design customisation - Since Apple watches run on watchOS, which draws from the iPhone's iOS, there are plenty of customisation options. You can play around with the style and colour of icons, wallpaper, etc.
Apple Watch Series 7

Apple Watch Series 7

  • 2021 | On sale
  • Latest Apple Watch series
  • Increased brightness of the always-on display
  • Variety of health and sports features

Apple Watch Series 7 comes with a visibly larger display, while the case itself remains almost unchanged. This has allowed the bezels to be thinned by 40%, allowing for 20% more content to be displayed between generations. Compared to the Apple Watch Series 3, this is an increase of a respectable 50%, and many third-generation owners can be expected to upgrade to the Apple Watch 7. The buttons in some apps, such as the stopwatch, timer and calculator, have been redesigned and are more intuitive to use than ever before. The QWERTY keyboard is also new, allowing you to swipe between letters without lifting a finger for even faster and more accurate typing. It's also more efficient to draw characters with your finger alone, making interacting with Apple Watch 7 a pure joy.

While Apple Watch Series 7 still doesn't have noticeably more battery life, charging itself has increased by 33% between generations. You can get enough power for 8 hours of sleep tracking in just 8 minutes, and 80% of the battery can be charged in just 45 minutes. This means that Apple Watch 7 doesn't need to be recharged on purpose, but can just be put on the charger while you enjoy your shower.

The Apple Watch 7 smartwatch arrives in a variety of attractive designs that vary in material and colour. You can choose from titanium, stainless steel and 100% recycled aluminium, which will come in five new colours – green, blue, starlight, midnight and (PRODUCT)RED.

Advantages and Disadvantages

  • Even better always-on display
  • New 41 and 45mm editions
  • Overall more durable design
  • Relatively few innovations
Apple Watch Series 6

Apple Watch Series 6

  • 2020 | On sale
  • Advanced health functions (blood oxygen level, ECG)
  • S6 dual-core processor
  • Available in multiple colours
  • Optional extra pay for the stainless steel version
  • New strap types (still compatible with older editions)

The Apple Watch 6 boasts premium craftsmanship down to the smallest detail. From the first glance, you'll be impressed by the beautiful OLED display with high finesse, premium colours and automatic brightness adjustment of up to 1,000 nits. And compared to Apple Watch 3, you get a 30% bigger picture, which, in combination with narrower bezels, is truly noticeable. There's also an always-on display. Another highlight of the Apple Watch 6 is the operating system, which offers one of the most sophisticated environments ever. Particularly original is the menu made up of individual app icons, which is extremely clear and intuitive, although those interested can also opt for a line menu. Fortunately, the emphasis on the best possible appearance has not resulted in any system lag either. Everything is perfectly smooth, thanks in particular to the dual-core 64-bit processor that is part of the new S6 chip.

The Apple Watch 6 key features are health-related. We can rely on all-day heart rate monitoring, including alerts for abnormal fluctuations, even though the measurements are taken every few minutes, so sudden changes may not be detected in time. The data is more accurate than ever thanks to the third generation optical sensor, which also measures blood oxygenation and ECG, one of the rarest functions ever. Another original feature is the automatic start of a 20-second countdown when washing hands, although this is sometimes activated by dishwashing. Another distinctive feature is the continuous noise measurement, which immediately alerts us to excessively noisy surroundings. Of course, there's also sleep monitoring, but it has trouble detecting it automatically, so, unfortunately, beeping alerts can disrupt your sleep. Stress monitoring is also cannot be missing, although surprisingly the data is only available in the mobile app, which can be a bit stressful with such an interesting indicator.

Like its predecessors, the Apple Watch 6 has a relatively limited battery life of just 18 hours. However, the practical experience is all the more surprising, with the watch lasting around a day and a half without any problems.

Advantages and Disadvantages

  • Excellent health features
  • Powerful S6 processor
  • Now officially available in Cellular edition (calls possible even without an iPhone)
  • Real battery life is about 1.5 days
  • Battery life is still shorter than most other smartwatches
  • Some watch faces are only available for AW 6
Apple Watch SE

Apple Watch SE

  • 2020 | On sale
  • Functionally limited Watch Series 6 edition
  • Cellular version available
  • Eye-catching colour options

If you're on a budget but still want an Apple Watch, the SE series is the way to go. It's based on the Watch Series 6, so you're guaranteed years of software support. It is a better option than buying one of the older generations second-hand.

How did Apple manage the lower price tag? Most notably, the lack of the latest health features in the form of ECG or blood oxygenation measurements. Also, the watch does not have an always-on display, which continuously displays the most important information even without activating the display. However, everything else has been retained, so you can understandably look forward to a plethora of attractive bands or interesting dials.

Advantages and Disadvantages

  • Well-readable display
  • Powerful processor
  • Altimeter always active
  • Long support for watchOS updates
  • Digital Crown with haptic response
  • Price could be lower

The main innovation of this generation is the Always-On display, which constantly shows the clock face without you having to raise your wrist. This ensures that any important information is viewable discreetly. Despite fears to the contrary, the watch is optimised, so the new features do not significantly affect battery life.

Advantages and Disadvantages

  • Always-On display
  • Powerful processor
  • New materials
  • Compass
  • The battery life is shorter than most other smartwatches
  • Relatively few innovations compared to AW4
Apple Watch Series 4

The fourth Apple Watch series came with a larger display and, for the first time, an ECG sensor. This isn't the only reason why the AW4 has become one of the most popular sports and health watches. It can also recognise heavy falls and detect when you are immobile. It can even alert emergency services. The processor is also much more powerful than the previous version.

Advantages and disadvantages

  • ECG sensor
  • Powerful processor
  • Bluetooth 5.0 support
  • Lots of safety features
  • Support from iPhone 6S and beyond
Apple Watch Series 3

Apple Watch Series 3

  • Powerful processor
  • Up to 18-hour battery life
  • The eSIM option allows you to make and take calls
  • Older technology
  • No longer supports iPhone 5

Do Apple Watch work on Android phones?

It is not possible to use an Apple Watch with a phone running on Android. If you're connecting an iPhone and Apple Watch, it's not just about a Bluetooth connection, as many people think. Apple Watches run using encrypted data sent directly from iPhones. To pair your iPhone and Apple Watch, an encrypted connection is created, which Android smartphones are unable to establish. It is possible that this could be done with the help of an app, but no such app exists at this time and it would have to be released by Apple.

Can I make calls using an Apple Watch?

While older Apple Watch models can handle calls in place of an iPhone, the iPhone still handles the transfer between subscribers and must be within range of the Watch. It wasn't until the Apple Watch Series 3 in the Cellular version that the Apple Watch offered full phone-free calling thanks to an electronic SIM card - an eSIM that can use the same phone number as the phone. There's one catch, however. You'll need to buy an Apple Watch with Cellular or LTE for this feature. Then you need to contact your cellular carrier to activate a special plan for the Apple Watch.

Is the Apple Watch waterproof?

Apple Watches from the older series are only water-resistant, not waterproof. This means that if you get a little water on your watch, you can  wipe it away without causing  damage but you can't swim with it.

This does not apply to Apple Watch Series 2 and beyond. They are waterproof to a depth of 50m (5ATM). As soon as you start swimming, your watch automatically locks to prevent unwanted clicks. Once you get out of the water, just turn the digital crown. The watch unlocks and drains out any water.

What are the Apple Watch series'?

  • Apple Watch 2015 (April 24, 2015)

 Apple took a step into the unknown with their first release but this series has proven to be a great success.

  • Apple Watch Series 3 (September 23, 2017)

Series 3 is very different from its predecessors and took the watch to the next level. For the first time, you can call directly from your watch and discover the exclusive Hermès Edition design.

With Series 4 came design changes, in particular, a slightly larger display. The series also introduces the ECG feature and focuses on the wearer's health - the watch can monitor your vital signs and call for help if you are immobile.              

  • Apple Watch Series 5 (September 20, 2019)

  • Apple Watch Series SE (September 18, 2020)

Apple Watch SE is a functionally limited edition of the Series 6. The manufacturer decided to go to a lower price level, so the SE version removed the advanced health features in the form of ECG and blood oxygen level measurement. There is also no Always-On display.

  • Apple Watch Series 7 (September 14, 2021)

The brand new Apple Watch Series 7 is a celebration of technical excellence. Apple has done some pretty big things. For example, they've made the display 20% bigger and the charging time 33% faster.
