Casio lists four black-and-gray G-Shock watches in Japan

Casio has listed four new G-Shock watches in Japan, with orders available through its Japanese website.

The models update the 5600, 6900 and 5900 designs in a black-and-gray color scheme rather than the brighter colors often used for G-Shocks.

Their cases combine matte resin with metal details, while the DWE-5600MTM-8 has a mixed-material strap and a mesh-patterned face.

All four include shock resistance and water resistance to 200 meters, along with stopwatches, timers and LED backlights.

The 5600 and 6900 models have batteries rated for about five years, while the 5900 has a 10-year battery and world time.

Prices range from ¥15,950 to ¥28,050, with the mixed-material model costing the most.

They are listed for order in Japan, but no availability elsewhere is stated.
