White Skeleton S-Series Watch GMA-S2100SK-7AER

The Watch

Discover this stunning resin case reinforced with carbon fiber for exceptional durability. Measuring 42.9 mm wide, 46.2 mm long, and 11.2 mm thick, this model delivers a distinctly sporty, urban look. A mineral crystal protects the feature-packed dial, while four pushers on either side of the case give you full control over the watch's functions. To top it all off, the screw-back case back ensures 20 ATM of water resistance for your aquatic adventures.

The Dial

Round in shape, its gray color adds a lively touch to any outfit. The dial is packed with features: a day counter sits at 9 o'clock, while a digital screen displaying Arabic numerals at 5 o'clock handles functions like the stopwatch. Two central hands indicate the hours and minutes, benefiting from a Neobrite coating for easy night reading thanks to a fluorescent compound. The minutes are marked by a railroad track, and the hours by rivet-style indices. The "G-Shock Casio" logo appears at 12 o'clock.

Functions

LED Illumination: The watch dial is illuminated by a light-emitting diode.

Shock Resistance: The shock-resistant structure protects the watch against impacts and vibrations.

Neobrite Coating: The hands and/or indices feature a fluorescent coating that continues to glow in the dark after exposure to a light source.

World Time Function: The world time function displays the current time in 29 time zones and major cities around the world.

Stopwatch 1/100 sec - 24 Hours: Measures elapsed time to 1/100th-of-a-second precision, up to a maximum of 24 hours. An audible signal confirms the start and stop of the stopwatch.

Countdown Timers - 1/1 sec - 24 Hours: For precision lovers: countdown timers alert you to important or recurring events with an audible signal at the set date and time. Time can be programmed in seconds, up to 24 hours in advance.

5 Daily Alarms: An audible alarm reminds you of your daily commitments at the set time. This model features five independent alarms so you can stay on top of all your important appointments with total flexibility.

Hand Shift Function: This function moves the hands out of the way when they obstruct the time, date, or stopwatch display.

Key Beep On/Off: The key beep can be disabled using the mode button. Once turned off, no beep sounds when switching between functions. However, any programmed alarms or countdowns remain active after the key beep is disabled.

Auto Calendar: Once set, the auto calendar always displays the correct date.

12/24-Hour Time Format: Display time in either 12-hour or 24-hour format.

3 Years - 1 Battery: The battery powers the watch for approximately 3 years.

The Movement

This watch is powered by a Japanese quartz movement, driving both hands and all additional functions with precision.

The Bracelet

Matching the dial, a transparent white resin bracelet delivers both durability and robustness, along with all-day comfort. It fastens with a classic pin buckle for the perfect wrist fit.

Water Resistance

This model offers water resistance to 20 atmospheres, equivalent to 200 meters. This is a watch built for serious aquatic adventures - including freediving. You can even use a high-pressure washer while wearing it. Shower, bath, vigorous swimming, and freediving are all fair game. For scuba diving with tanks, we recommend a timepiece with a higher water resistance rating. Avoid operating the crown or pushers while submerged to protect the movement's integrity.
