Before the S Series there was the G-Shock Mini which came to the U.S. for the first time in 2009. The G-Shock Mini watches were based on classic G-Shock models and included the GMN-691 and GMN-692 (based on the DW-6900), the GMN-550 (based on the DW-5500), and the GMN-50G (based on the analog-digital AW-500). The G-Shock Mini models are 30% smaller than their counterparts. They were originally marketed to women but are available in some unisex colors and are suitable for men and children who want a smaller G-Shock. They also make for interesting collectibles as production has been discontinued. The G-Shock Mini line features shock resistance, water resistance to 100 meters, auto EL backlight with afterglow, world time (48 cities), 5 daily alarms, stopwatch, countdown timer, and 12/24 formats.
The following G-Shock Mini models are still available. As these watches are older models the battery may not last very long. For newer smaller watches look into the G-Shock S Series or the Casio Baby-G brand which also features shock resistance.
