The Spring Drive 200m Diver’s watch has long been appreciated for its precision and robustness. This version features a case made of high-intensity titanium which is lighter than stainless steel and more resistant to scratches. Its legibility at depth is 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. To ensure that the time can be read easily and without error at a glance, there are 60 distinct markings as well as five numerals on the bezel. Each hand is different in design and stands out clearly from the dial and the triangular marker at twelve o’clock ensures that, even at depth, no mistake is made. 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. This is why the titanium case and bezel are designed for secure disassembly and re-assembly when routine checks are made at the Grand Seiko Service Centers.
With its screw-down crown, one-way rotating bezel, water resistance to 200 meters and anti-reflective coating on inner surface of the crystal, this watch provides all the security and legibility that the serious diver requires.
