Casio G-Shock Gravitymaster watch, steel, GWR-B3000A-2AER

Blue Casio G-Shock Gravitymaster Watch with Steel and Carbon Fiber Case and Tough Solar

The dark blue textured dial and blue bio-based resin strap give this Gravitymaster watch a restrained color scheme, even though the construction is clearly technical. The angular case, made of stainless steel and carbon fiber, leaves the shock absorbers visible, and the bezel carries city codes for world time.

This Master of G series watch is powered by a Tough Solar cell, and the time is adjusted by Multi Band 6 radio signal and by Bluetooth through the CASIO WATCHES app. The watch has a stopwatch, timer, alarm, world time, direct UTC shortcut, flight log, date and a white LED light. The sapphire crystal has an anti-reflective coating. Water resistance of 200 m / 20 atm is enough for swimming and water sports, but not for scuba diving.

Frequently asked questions

Is the watch suitable for swimming or diving?
Water resistance is 200 m / 20 atm, so the watch is suitable for swimming, water sports, snorkeling and free diving. It is not a diving watch, so it is not recommended for scuba diving. Do not use the buttons underwater.

Does the watch need a battery change?
The watch is charged from light by the Tough Solar cell, so you do not need to change the battery. When fully charged, the battery lasts about 5 months with normal use without light and up to 22 months in power saving mode.

How does the watch keep the correct time?
The watch adjusts the time by Multi Band 6 radio signal. When you connect the watch to the CASIO WATCHES app via Bluetooth, the time is also synchronized through your phone.

Is the watch suitable for a small wrist?
The strap fits wrists of 145–215 mm. The case width is 47.3 mm and the thickness is 14.1 mm, so the watch is large in size.
