A hi-beat 200m diver’s watch with the highest specifications
With its screw-down crown, distinctive hands generously coated with Lumibrite, one-way rotating bezel and water resistant to a depth of 200 meters, this watch provides all the security and legibility that the diver requires. It also offers the precision and durability of Grand Seiko's divers' high-beat movement, Caliber 9S85.
Each hand is different, to ensure that the time can be read easily and without error that they stand out clearly from the dark blue dial. The triangular marker at twelve o’clock ensures that, even at depth, no mistake is made.
Every component is built to last, but all divers know that their watch needs regular maintenance, just like every other device on which his or her life may depend. This is why the case, stem pipe and crown are designed for secure servicing and even the bezel has a four-part design that makes for easy disassembly and re-assembly at the Grand Seiko Service Centers.
