![Grand Seiko Diver's Watch](https://www.theseikoguy.com/media/2022/05/grand-seiko-divers.jpg)
In 2008, the first Grand Seiko diving watches were introduced: the reference SBGA029 (9R65-0AM0) in stainless steel, and the SBGA031 (9R65-0AN0) in titanium, both featuring the Spring Drive caliber 9R65.
The creation of these watches find its roots in the long journey Seiko started with the 62MAS in 1965, and in the progressive improvements to get closer and closer to an ideal of perfection.
Although Grand Seiko diver’s watches have the typical characteristics of luxury watches, starting with the quality of the finishes and movements, they manage to maintain the robustness of the most reliable tool watches that Seiko has accustomed us to.
