Seiko Turtle Diver: SRPH17K1, caliber 4R35, 200m water resistance
Collection
The Seiko SRPH17K1 belongs to the Prospex range, a series of sports instruments. The Turtle model—named for its characteristic curved case—reprises the silhouette of Seiko divers from the 1970s, revisited in a 44.3mm case with a 4R35 caliber and 200m water resistance. Its unidirectional bezel and luminous markers make it operational for diving as well as on the surface.
Case
The case of the Seiko SRPH17K1 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 treatment. The case back is solid and screwed down. Water resistance is 200 m, compliant with ISO 6425 diving standards. The markers and hands are coated with LumiBrite, Seiko's luminescent material for extended night-time legibility.
Movement
The Seiko SRPH17K1 is powered by the automatic caliber 4R35, 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.
Bracelet
The Seiko SRPH17K1 is equipped with a stainless steel bracelet, which is both robust and easy to maintain, fastened by a deployment 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.
