Casio G-SHOCK GA-100 Series an Analog-Digital Watch - GA100-1A1 BLACK

The Casio G-SHOCK GA-100-1A1 combines an oversized black case with a dark analog-digital display for a bold, low-key look. Large aluminum hands, symmetrical LCD windows, and an inset speed dial give the face depth while preserving the GA-100's practical timing functions.

The shock-resistant, magnetically resistant build is backed by 200-meter water resistance. A 1/1000-second stopwatch can calculate speed from a user-entered distance, while world time, a 24-hour countdown timer, and five alarms cover everyday timing and travel needs.
