Casio G7900-1 G-Shock Rescue Digital Sport Watch for Men

Featuring a round sport watch design with a four-point protection, large buttons and display format, as well as tide and moon-phase data, this product offers a range of impressive specifications. The 50 mm resin case houses a mineral dial window and a Japanese quartz movement with digital display. The resin band secures with a buckle closure and is water resistant up to 200 m (660 ft), making it suitable for professional marine activity and serious surface water sports, though not for scuba diving.

Shock resistant and equipped with low temperature resistant LCD (-20 C / -4 F), the watch boasts an Auto EL backlight with afterglow, as well as a flash alert feature that flashes with a buzzer for alarms, hourly time signals, countdown timer time-up, and stopwatch auto-start. The tide graph provides the tide level for a specific date and time, while the moon data displays the moon age and phase graph.

With world time functionality covering 29 time zones (48 cities), the watch also offers 4 multi-function alarms, 1 snooze alarm, and an hourly time signal. The countdown timer ranges from 1 minute to 24 hours, with measuring units of 1 second. The 1/100 second stopwatch modes include elapsed time, split time, and 1st-2nd place times, with a 5-second auto-start feature.

Other notable features include button operation tone on/off, an auto calendar pre-programmed until 2099, and 12/24 hour format options. The watch is powered by a CR2025 battery with an approximate 2-year lifespan.

Casio's history in the wristwatch market dates back to the launch of its first watch in November 1974, a time when the industry was just beginning to explore digital technology. As a company with cutting-edge electronic expertise developed for pocket calculators, Casio entered this field confident in its ability to lead the market with innovative timepieces.

Today, Casio's focus is on solar-powered radio-controlled watches, eliminating the need for battery replacement and ensuring accurate timekeeping. The company has also recently introduced a series of Bluetooth-enabled watches that synchronize with the user's smartphone to automatically update the time. Casio's commitment to pushing the boundaries of watch technology is evident in its continuous efforts to move time forward.
