Delving into the heart of Seiko's JDM watches, we marvel at the new engine that this renowned company has built. 2005 marks the year in which Seiko made the 6R15 engine, derived from its 7S26 movement.

This movement is used to power the Sumo Japan Blue edition, making this timepiece the first to feature Seiko's new automatic caliber. Maintaining operation at 21,600 BPH (3 Hertz) with hacking and hand winding capabilities, this engine has 24 jewels and a longer power reserve of 70 hours, a whopping 20 hours more than the 7S and 6R. The 200m water resistant Sumo stainless steel case embodies the beautiful craftsmanship and fluid line.
