Seiko Divers Prospex ‘Great Blue’ Sumo PADI Special Edition, SPB3375J1. Introducing a new PADI Special Edition Diver’s watch, continuing the Seiko Prospex association with the globally renowned Professional Association of Diving Instructors.This watch shape is affectionately named ‘Sumo’ by Seiko fans because of its size and shape and the 12 o’clock marker – it’s a substantially strong looking timepiece.The dial of this design was influenced by a diver’s underwater view as the sun reflects and shines on the surface. The light blue coloured minute hand and scale on the bezel allows for high legibility in deep water.It operates on an in-house mechanical 6R35 calibre movement, 70-hour power reserve, and is water resistant up to 200m. The case is made of stainless steel with a super hard coating. The bracelet comes with a newly refined Diver buckle design. It has sapphire glass, and a date display on the dial.The PADI timepiece collection is exclusive to Seiko, as the only global watch brand to design a range of professional diver’s watches in official colours featuring the PADI logo. PADI (The Professional Association of Diving Instructors) is the world’s leading scuba diving training organisation, unifying divers around the globe who share a passion for adventure and love for the ocean. Proceeds from each Seiko Prospex watch are donated to support the PADI Ocean Cleanup campaign.Prospex is a combination of the words ‘Professional’ and ‘Specifications.’ Seiko Prospex timepieces are designed to be practical, reliable and durable; to meet the high standards required in extreme environments for sports lovers and adventure seekers alike.* In the real watch, the caseback direction may differ from the photograph
