Description

Introducing the Casio G-Shock GA-B2100C-9AER, a burst of color that redefines the iconic GA-2100 aesthetic. Its bright yellow octagonal resin case contrasts dramatically with the matte black dial, creating immediate visual impact. Silver rectangular indices stand out against the black background, while the vibrant yellow subdial at 9 o'clock mirrors the case color. Silver luminescent hands ensure readability in any condition. The textured yellow resin strap completes the ensemble with an unmistakable design.

At its heart beats the Casio module 5689, an analog-digital caliber with Bluetooth connectivity and Tough Solar power. The circular subdial displays digital information including day, date and secondary functions. Key capabilities include: world time with 38 time zones, 1/100 second stopwatch up to 24 hours, countdown timer, 5 daily alarms, power saving function and automatic Bluetooth synchronization with smartphones. Connectivity enables remote adjustments, phone finder and activity logging.

The G-Shock collection was born in 1983 with engineer Kikuo Ibe's vision to create an unbreakable watch. After over 200 prototypes and 10-meter drop tests, the first generation emerged with floating structure that absorbed impacts. The GA-B2100 series evolves this legacy by incorporating solar technology and Bluetooth connectivity, maintaining legendary toughness with contemporary design.

Title : Great watch!
Comment : Great watch. Great price. Prompt delivery to the UK. The watch looks fantastic in yellow. Easily one of the best-looking G’s ever made. It doesn’t feel quite as sturdy as my GW-M5610U-1ER. However, it does still seem like it can take a beating and keep working.
