A diver’s watch powered by Spring Drive

Grand Seiko’s first diver’s watch is an essential underwater companion, offering everything a recreational diver needs with no compromise or distracting ornamentation. The beautifully finished case is built to withstand the shocks and pressures that come with serious underwater activity, and the multi-faceted LumiBrite indexes are affixed onto the dial by a swaging process that ensures their resistance against shocks. The rotating bezel is designed for simple maintenance and the area around the crown has been crafted to ensure that residue from dirt, sand, or seawater can be easily washed off. SBGA229 is water resistant to a depth of 200 meters, but its versatility means that it’s perfectly suited for dry land, too.
