Seiko Prospex PADI 60th Anniversary 4R Compact Mechanical Diver’s Watch Underwater Green SRPL53

This Seiko Prospex diver’s watch has been created in collaboration with PADI – the Professional Association of Diving instructors, the world’s most recognised diver’s training organisation. It commemorates 60 years of Seiko watchmaking heritage in Diver’s watches.

Continuing the Seiko heritage of watchmaking innovation and design evolution, this Prospex diver’s watch is evolved from a combination of two popular Seiko designs. Nicknamed by fans for their unique case shapes, the ‘Samurai’ and ‘Shōgun’ are popular Seiko models which are angular in shape and instantly recognisable. This latest Compact diver’s watch takes elements from both heritage designs, as well as adding modernised features. Aesthetically, the green dial depicts the surface of the ocean seen by a diver underwater, with the sunlight pouring through. It takes the steep angled lugs of the Shōgun and echoes the crown design of the Samurai model with the straight contours of both blueprints.

In terms of size, this piece has a compact 41.7mm diameter case and slim design for comfortable wearability. Its new features include a date window at 4.5 o’clock, pointed hands, and a bracelet with press-formed integral links for an elegant feel that matches the linearity of the case. This watch is compliant with the recognised ISO standards for professional diving watches. It is water resistant to 200m.

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.
