The Casio Solar Atomic G-Shock Watch GW2310FB-1 promises to be as popular as the original Tough Solar model, G2310 that was introduced back in 2001. In fact, this newer high-performance watch from Casio was modelled after the GW2310FB-1 because it was that popular. This newer watch is more powerful than ever yet it retains the classic, utilitarian case shape of its predecessor for classic yet rugged styling.

This water-resistant watch now includes a multi-band Atomic timekeeping for use in the US, UK, Germany, Japan, China and receives time calibration radio signals to keep the displayed time as accurate as possible. The auto receive function works up to six times per day and up to five times per day in China. These features alone make this watch highly desirable for those military operators or civilian enthusiasts who have a very high need for accuracy.

The manual receive function signal on this shock-resistant watch operates at US WWVB, UK MSF, Germany DCF77, Japan JJY40/JJY60, China BPC. The frequency operates at US 60kHz, UK 60kHz, Germany 77.5kHz, Japan 40/60kHz and China BPC 68.5kHz. This all-important feedback keeps you on time and on target no matter where you are in the world and in what time zone.
