Featuring the Seiko mechanical automatic 6R35 movement, the SPB103J1 has an accuracy tolerance of +25 /- 15 seconds per day. This model is finished in full Stainless Steel. The hands and the markers have lumibrite to make them visible at night (once fully charged). The case size is 45mm and thickness 12.9mm and the entire watch weighs approximately 190gm. Being a 200m dive watch, features include a screw lock crown, a screw case back and a uni-directional rotating bezel. Additional features include a date function and a stop seconds hand function.

What we love: The finish and the clean look. The green dial along with the overall finish of the model. Destined to be a Seiko cult classic model. Feels solid on the hand. Made in Japan. Images don't do this watch justice.
