Prospex Land Tortoise 42mm Automatic Diver

The Seiko Prospex Land Tortoise SRPG18J1 is a 42mm automatic diver built for men who want a capable sports watch with a distinctive brown dial. Its rose gold tone stainless steel case and leather strap suit daily wear and outdoor activity alike.

Sapphire crystal and screw-down crown simplify

A sapphire crystal resists scratches during regular use while the screw-down crown secures the 200m water resistance when the crown is fully tightened. The leather strap fastens with a buckle clasp for straightforward adjustment on the wrist.

Caliber 4R35 delivers steady daily performance

The automatic caliber 4R35 with 23 jewels maintains consistent timekeeping through extended wear without relying on a battery. Its 200m rating supports recreational diving and prolonged water exposure rather than brief splashes alone.
