Grand Seiko Sport Divers Spring Drive Mens Watch SBGA461G

The Spring Drive 200m Diver’s watch has always been appreciated for its precision and robustness. Now, its legibility at depth is further enhanced by the inclusion of Lumibrite indexes at all twelve hour marks, including the one at three o’clock to the right of the calendar frame. Every component is built to last but every diver knows that their watch needs regular maintenance, just like every other device on which his or her life may depend.
