More Information


Casio GA-100B 4A is a watch with an interesting design with a number of handy innovative features. The very basis is the average speed indication function - at the beginning, simply enter the length of the journey and upon completion press the stopwatch button. There's also a snooze function that repeats the alarm after a few minutes after having been put on snooze. One of the more common features is represented by the world time function that is capable of displaying local time in various cities and specific regions all over the world without any difficulties. A stopwatch and a timer are of course included as well. The case and the band of the band are made of resistant synthetic resin. Due to its carefully crafted construstion, the watch is resistant to shock, vibrations and the effects of magnetic fields.

Advanced stopwatch

Elapsed time is measured with an accuracy of one thousandth of a second. The maximum tracking length is a decent amount of 100 hours. The stopwatch also has an acoustic signal for the start and the stop of the measuring.  A countdown timer is also included, an audible sound signal notifies you of the completion. The maximum length of the countdown is 24 hours and it can be set in one-minute intervals. Undoubtedly, the biggest perk of the timer is the automatic repeat function in a set time.
