Seiko Prospex Land Tortoise Automatic Diver

The Seiko Prospex Land Tortoise SRPG15J1 is a new automatic diver's watch built for men who need a capable mechanical tool watch. A stainless steel case houses the 4R35 caliber with 23 jewels, protected by a sapphire crystal and a screw-down crown. It delivers 200m water resistance and a rotating bezel for timing dives.

Strap choice and thickness define the fit

The integrated polyester strap and buckle clasp suit wearers who prefer a lightweight, quick-drying band over metal bracelets or rubber. Buyers who want a bracelet included, a slimmer case profile, or a different strap material should look elsewhere.

4R35 automatic caliber with 23 jewels

The 4R35 movement provides three-hand analog timekeeping with a date window driven by 23 jewels. It winds automatically through wrist motion and can be hand-wound via the screw-down crown. This caliber is the sole specification that determines whether the watch matches your movement preference.

Questions about this item

How do I set the time and date on the 4R35 movement, and which crown position do people often miss?

Pull the screw-down crown to the first click for date, second click for time; many forget to push and screw it back fully to keep 200 m water resistance.

What part of the 23-jewel automatic movement will need service first, and roughly when?

The mainspring lubrication inside caliber 4R35 typically requires a watchmaker's clean and re-oil every three to five years.

At what depth does the 200 m rating stop protecting the sapphire crystal and screw-down crown during continuous diving?

The 200 m limit is the tested static pressure ceiling; beyond that the case seals and crystal retention are no longer guaranteed.
