Seiko PROSPEX Diver Scuba Mechanical Automatic Core Shop Exclusive Wristwatch Mens Sumo SBDC083

The model affectionately known as "SUMO" from Prospex has been renewed with a smart and modern impression. Since its release, the commonly referred to "SUMO" has become a long seller both domestically and internationally, now featuring the newly developed long power reserve movement "Cal.6R35." While inheriting the iconic elements derived from SUMO, it has evolved into a specification and design suitable for a global model. The "bezel scale," "index," and "hands" have been transformed to create a smart and modern impression. Notably, the second hand and minute hand have been extended to the torque limit, enhancing visibility and practicality. This model boasts high functionality as a diver's watch while also being stylish enough for town use. / Caliber: 6R35 / Power reserve: approximately 70 hours at maximum winding / Accuracy: daily variation +25 seconds to -15 seconds / Number of jewels: 24 / Hacking function / 200m water resistance for diving / Calendar (date) function / Unidirectional rotating bezel / Screw back / Screw-lock crown / Double-lock clasp / LumiBrite: (hands and index) / Magnetic resistance type 1 / Band adjustment: C-ring method / MADE IN JAPAN Package weight: 0.56 kg Type: Plain Target gender: male
