Questions

What is the Japanese version of the Seiko SSK036?

In Japan the SSK036 is sold as the SBSC020: the same 4R34 calibre, the same 42.5 mm case and 100 m water resistance. Only the reference differs by market.

What movement is in the Seiko SSK036?

The SSK036 runs on the Seiko 4R34, an automatic movement that can also be wound by hand. See the 4R34 page for its specs and every watch built on it.

Does the Seiko SSK036 have a sapphire crystal?

No. The SSK036 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 SSK036?

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 SSK036?

22 mm. Any 22 mm strap fits.
