Seiko Prospex Men's Automatic Watch SRPJ35K1 Turtle Tropical Lagoon

The Seiko Turtle Diver: SRPJ35K1, Caliber 4R36, 200m Water Resistance

Collection

The Seiko SRPJ35K1 is part of the Prospex line, a series of sports instruments. The Turtle model—named for its characteristic domed case—retains the silhouette of Seiko divers from the 1970s, revisited in a 44.3 mm case with a 4R36 caliber and 200m water resistance. Its unidirectional bezel and luminous indices make it operational for diving as well as on the surface.

Case

The case of the Seiko SRPJ35K1 is made of stainless steel, with a diameter of 44.3 mm and a thickness of 13.4 mm. The unidirectional rotating bezel allows for precise measurement of dive times. The black dial is protected by a sapphire crystal, the most scratch-resistant, with anti-reflective coating. The case back is solid screw-down. The water resistance is 200 m, compliant with ISO 6425 diving standards. The indices and hands are coated with LumiBrite, Seiko's luminescent material for extended night readability.

Movement

The Seiko SRPJ35K1 is powered by the automatic caliber 4R36, offering a power reserve of approximately 41 hours. It includes hacking (stopping the second hand for precise time setting) and manual winding, two conveniences absent on the previous generation 7S26 caliber.

Bracelet

The Seiko SRPJ35K1 is equipped with a stainless steel bracelet, both robust and easy to maintain, fastened by a folding clasp, which makes it easy to put on and take off the watch while securing the bracelet to the wrist. The lug width is 22 mm.
