analog‑digital “2100 Series” Casio G‑Shock with full black band, green dial, and a metal bezel — written to sound authentic and not exaggerated. Since the exact variant may not officially exist, this is based on similarly styled models and general product knowledge.

Features a matte black resin band, paired with a dark‑ion‑plated stainless steel bezel, giving a stealthy, rugged look. The eye‑catching green dial is vertically brushed, glowing emerald in sunlight—otherwise darker indoors. This look resembles the popular GM‑2100B‑3A (“emeral‑green dial”) but with a black strap and darker bezel tone. ([turn0search5]turn0search11)
Completed in a slim octagonal “CasiOak”-inspired case measuring around 44 mm in diameter and ~11.8 mm thick, weighing about 72 g. ([turn0search4]turn0search13)
If It Were an Official Model, Key Features Might Be:
- Shock-Resistant & 200 m Water Resistance: typical for GA‑2100/GM‑2100 models
- Analog-Digital Display: sleek hands over a small digital window, both visible under laminate
- Mineral Glass: scratch-resistant crystal over the dial
- Metal-Clad Bezel: forged and polished, with IP coating for durability and premium finish
- Functions: stopwatch, countdown timer, world time, 5 alarms, full auto-calendar through 2099, hand-shift (moves the hands out of the way) and super-illuminator backlight
