The Seiko Sumo SPB101J1 is a diving watch from the Prospex line, introduced in Europe in 2019. This model, previously available only in Japan, is equipped with the 6R35 automatic movement with 70 hours of power reserve and sapphire crystal. The 45 mm steel case, with rotating bezel and screw-down crown, guarantees water resistance up to 200 meters. The dial is highly legible, even in low light conditions, thanks to luminescent indexes and hands. The steel bracelet with micro-adjustment completes its functional and robust features.
