Seiko Prospex Automatic Men's Watch SRPF77K1 King Turtle Blue Save The Ocean Edition

For the Oceans: The Prospex Blue Automatic 4R36, 200m Water Resistance

Collection

The Seiko SRPF77K1 is part of the Prospex Save the Ocean collection. Each watch in this range is linked to an ocean protection program, and its design is inspired by the marine world — here, a blue dial reminiscent of the deep. Technical specifications: 44.3mm case, 4R36 caliber, 200m water resistance.

Case

The case of the Seiko SRPF77K1 is made of stainless steel, with a diameter of 44.3mm and a thickness of 13.4mm. The unidirectional rotating bezel allows for precise measurement of dive times. The blue dial is protected by a sapphire crystal, the most scratch-resistant, with an anti-reflective coating. The case back is solid and screwed down. Water resistance is 200m, conforming to ISO 6425 diving standards. The indices and hands are coated with LumiBrite, Seiko's luminescent material for prolonged nighttime legibility.

Movement

The Seiko SRPF77K1 is powered by the automatic caliber 4R36, offering a power reserve of approximately 41 hours. It includes hacking (stop seconds for precise time setting) and manual winding, two conveniences absent on the previous generation 7S26 caliber.

Strap

The Seiko SRPF77K1 is equipped with a silicone strap, flexible and resistant to water and perspiration, secured by a classic and easy-to-adjust pin buckle. The lug width is 22mm.

Supplied with: Storage box, presentation pad, user manual.
