G-Shock Mudmaster GSG-100-1A

Costco has the stealthy G-Shock Mudmaster GSG100-1A (listed as GSG-100-1AWC) available in the U.S. for $169.99, which is surprising as this model and series were thought to have been discontinued a while ago. (Note: Non-members can order online but will be charged an additional 5%.) The GSG-100 features Tough Solar power and mud-resistant buttons. In addition to Neobrite luminous hands and marker tips, the watch has a full auto double LED light with LCD backlight and Neon Illuminator. The Neon Illuminator is a black light LED that provides additional illumination on certain areas, and in this case that includes six hour markers and the tips of the hands, as seen in this Indowatch video on YouTube). The original price of the GSG100-1A was $330, so this is a discount of around 48%. (The GWG-100-1AJF with Tough Solar and Multi-Band 6 is still available in Japan.)

The watch measures 56.2 x 54.9 x 17.3 millimeters and weighs 88 grams. Other features include shock resistance, 200-meter water resistance, world time, 1/100-second stopwatch, countdown timer (100 minutes max), five daily alarms, full auto-calendar, and hand shift.
