Key Features

3. Dual Illumination System
   The watch features a dual illuminator—LED backlight for the digital display and Neobrite luminous coating on the analogue hands—ensuring readability in any lighting condition. The adjustable illumination duration (1.5 or 3 seconds) adds convenience.

4. Hybrid Analogue-Digital Display
   A sleek analogue face is complemented by a small but functional digital display, offering multiple functions including a stopwatch, countdown timer, world time, and alarm.

5. Minimalist Octagonal Design
   The octagonal bezel gives this G-Shock a refined, almost luxury-inspired look while maintaining its signature toughness. The black-on-black colour scheme exudes understated sophistication.
