Seiko Prospex Automatic Men's Watch SRPG18J1 Land Tortoise

Brown Prospex for Diving and Adventure: SRPG18J1, 40.5 mm, 50 m

Collection

The Seiko SRPG18J1 is part of the Prospex line, the brand's high-end sports range. The Prospex collection has covered diving, altitude, and exploration since the 1960s; this 40.5 mm brown model with 50 m water resistance is a modern and accessible representative.

Case

Made of stainless steel, the case of the Seiko SRPG18J1 measures 40.5 mm in diameter and 12.6 mm in thickness. The unidirectional rotating bezel allows for precise measurement of dive times. The dial is protected by a sapphire crystal, the most scratch-resistant, with an anti-reflective coating. The case back is solid screw-down. The water resistance is 50 m, suitable for swimming and splashing. The indexes and hands are coated with LumiBrite, Seiko's luminescent material for extended nighttime readability.

Movement

The Seiko SRPG18J1 is powered by the automatic caliber 4R35, offering a power reserve of approximately 41 hours. It incorporates hacking (stop-seconds for precise time setting) and manual winding, two conveniences absent from the previous generation 7S26 caliber.

Strap

The leather strap of the Seiko SRPG18J1, fastened with a pin buckle, consistently complements the case. The lug width is 20 mm.
