Questions

What is the Japanese version of the Seiko SRPD53?

In Japan the SRPD53 is sold as the SBSA003: the same 4R36 calibre, the same 42.5 mm case and 100 m water resistance. Only the reference differs by market.

What movement is in the Seiko SRPD53?

The SRPD53 runs on the Seiko 4R36, an automatic movement that can also be wound by hand. See the 4R36 page for its specs and every watch built on it.

Does the Seiko SRPD53 have a sapphire crystal?

No. The SRPD53 has a Hardlex crystal. Hardlex is Seiko's hardened mineral glass: tougher than plain mineral glass, softer than sapphire.

How water resistant is the Seiko SRPD53?

100 m (10 bar). That covers swimming and snorkelling; it is not a certified diver's watch unless Seiko says so.

What is the lug width of the Seiko SRPD53?

22 mm. Any 22 mm strap fits.
