The base model is the GA-B2100, which retains the octagonal form of the GA-2100, but is equipped with a smartphone link and tough solar. By combining it with the carbon core guard structure, it maintains the size of the previous model. The base colors are black, green, and white, which are easy to match with a variety of fashion styles. By keeping the watch in one tone and using primary colors such as red, blue, yellow, and green for the bezel text, indexes, and small hand on the 9 o'clock side, we have created a model with a calm yet lively image. This model can be used in a wide range of situations, from casual occasions to outdoor festivals. ●Shock-resistant structure ●Tough solar (solar charging system) ●20 ATM waterproof function ●Mobile link function (function linked via Bluetooth® communication with compatible mobile phones) ●Hand retraction function (If the hands overlap the LCD display and are difficult to see, you can temporarily retract the hands from above the LCD display.) ●World Time: 38 cities around the world (38 time zones, automatic daylight saving time setting function included) + UTC (Coordinated Universal Time) time display, home time city switching function ●Stopwatch (1/100 second (less than 1 hour)/1 second (more than 1 hour), 24 hour meter, with lap/split) ●Timer (set unit: 1 second, maximum set: 60 minutes, measured in 1 second increments) ●5 time alarms/time signal ●Battery indicator display ●Power saving function (turns off the display after a certain period of time in a dark place to save power) ●Full auto calendar ●12/24 Time system display switching ●Operation sound ON/OFF switching function ●Date display (month/day display swap) ●Day of the week display (switchable between 6 languages: English, Spanish, French,...
