Functionally, the GA-B2100 comes with the usual plethora of features, all while keeping the dial relatively minimalistic, which is preferable for me because too much going on takes away from legibility and usability. The button tones for using the mode button can be turned off. This means that the watch no longer beeps when switching from one function to another. Preset alarm or countdown timers remain active when the button tones are deactivated. The new dial features a translucent surface, which is required to let the light through to power the battery. With this change, Casio opted to give the dial a new sunburst treatment, which not only adds solar power but also elevates the dial visually over the original CasiOak.

ALARM FUNCTION - 5 Daily Alarms: Each will sound every day at the time you set, Hourly time signal: The watch beeps every hour on the hour For those who want a CasiOak, and are adamant about having Casio’s desirable Bluetooth and Tough Solar technology, this should be of interest. And for those wanting the same tech, but housed in a metal-covered CasiOak, that’s also now an option, albeit, at a higher price point. You won’t find any other watch with the durability and tech found in the GA-B2100, for anywhere close to the price of this watch — making this a bargain.Elapsed time, split time and final time are measured with 1/100-sec accuracy. The watch can measure times of up to 24 hours. Casio create stylish and durable watches great for everyday wear. Their watches are instantly recognisable by their shape and colour. Despite being classed as a digital watch due to its multifunctionality and date display, time reading is analogue. Multi functional timepiece The watch is equipped with energy-saving Bluetooth® technology, which offers power-saving data transfer at the push of a button. The watch can connect to a smartphone wirelessly via Bluetooth®, enabling access to a wide range of useful functions. BATTERY LIFE - Approximately 18 months on rechargeable battery (operation period when stored in total darkness with the power save function on after full charge)

To conserve power, the watch display automatically goes blank to save power when the watch is left in the dark. The approximate battery operating time is 7 months on a fully recharged battery (with normal use without exposure to light after charge) and 18 months on a fully charged battery (operation period when stored in total darkness with the power save function on after full charge). In the Flight Log memory GPS precise location with time and date, can be opened by pressing a button. This function can e.g. be helpful for pilots much to their stakes to document and display it on maps later.
