Casio G-Shock FROGMAN Master of G Sea - GW-8230B-9A

Dive into the celebration of the 30th anniversary of
the G-SHOCK Master of G Frogman family of full-fledged
diver’s watches with ISO-standard 200-meter water
resistance. The ever-popular second-generation Frogman,
the DW-8200, made quite a splash when it launched back
in the 1990s1993, with its high-impact asymmetrical
design featuring a resin bezel and titanium case.
More than just a revival of this original design,
the GW-8230B represents a new evolution — it is
the first Frogman to use Earth-friendly biomass plastics
in the bezel & band. Add Tough Solar powered by a solar
panel designed especially to reproduce the shape of
the DW-8200 dial, and you have a special diver’s watch
that goes the extra mile to reduce environmental impact.
This limited edition reprises the a popular DW-8200B-9A
black and gold color scheme while adding high-tech
functions to bring state-of-the-art 21st century technology
to 1990s design. The back of the titanium case and the LED
backlight both display a special Frogman 30th anniversary
