Questions

What is the Japanese version of the Seiko SRPH63?

In Japan the SRPH63 is sold as the SBSA149: 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 SRPH63?

The SRPH63 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 SRPH63 have a sapphire crystal?

No. The SRPH63 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 SRPH63?

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