Grand Seiko Quartz diver
The best quartz dive watch in the World.
For the first time in Grand Seiko’s history, the introduction of the 9F high accuracy quartz movement has been placed into a new 200m divers design. There are two new models featuring the quartz movement. SBGX115 with a new white dial is the first, and the SBGX117 with traditional black matte dial is second. Both these models are in a 42.7mm stainless steel case that is 13mm thick and features Zaratsu polishing around the cases lugs. The models are mostly a brushed finish, including their stainless steel, 3 pieces oyster style bracelets.

These two watches are the closest to the platonic ideal of a tool watch as anything Grand Seiko has ever made. They have a super high accuracy, super low maintenance 9F quartz movement, a screw down crown, 200 meters of water resistance and a unidirectional rotating bezel. Any unnecessary flourish, like a date or day complication, a power reserve, a display back, has been totally removed. What remains is a very dedicated dive watch, drawing from Seiko’s roughly 50 year history in the field.

Hands on Grand Seiko Quartz models are large. The hours and minutes are titanium, with a long steel second hand. This is not typical to see in quartz movements, as they do not generally have the torque to push the heavy hands. Seiko uses a twin pulse motor that allows for the additional torque necessary. Typically, only one pulse will push the second hand once per second. The 9F moves at two steps per second and does so without any visual indication. This ends up saving energy, allowing for the 3 year battery life.

The new Grand Seiko Quartz diver is a sporty piece, equipped the 9F Quartz caliber, exclusive to Seiko, for an impressive +/- 10 second a year accuracy rating, 50 year service interval, and high shock and magnetic resistance JIS2 (16,000A / m) for harsh environments.

A newly designed bezel provides high accuracy and performance, and enables easy disassembly for maintenance. This new bezel has an edgy design and dynamic font that achieves high legibility and targeted towards younger customers.

This also includes the high quality Grand Seiko case polished by the beautiful Zaratsu technique giving a mirror finish. The hands are titanium with Seiko’s lumibrite for high legibility in dark waters.
