A compact construction designed for comfort
The reliability, safety, and ease of use required of a Seiko diver's watch are all provided for in the new, more compact design. With a case diameter of 40.0mm, a lug-to-lug length of 46.4mm, and a thickness of 13.0mm, the watch’s compact dimensions offer excellent wearability for everyday use. A new bracelet with shorter links and a smaller clasp allows the watch to conform to the wearer's wrist and provides a new level of comfort. The shorter lugs also ensure a high degree of wearability.
More power, greater water resistance, and enhanced legibility
Each watch is powered by one of Seiko’s latest in-house automatic movements, Caliber 6R55, which has a power reserve of 72 hours. The watches are further enhanced to ensure water resistance to 300 meters, a first for Prospex non-saturation diver’s watches. The date window has been moved to the space between four and five o’clock to allow for a more symmetrical design and more space to be filled with Lumibrite, ensuring high legibility even in dark conditions.
