Questions
What is the Japanese version of the Seiko SRPM07?
In Japan the SRPM07 is sold as the SBSA321: the same 4R36 calibre, the same 38.0 mm case and 100 m water resistance. Only the reference differs by market.
What movement is in the Seiko SRPM07?
The SRPM07 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 SRPM07 have a sapphire crystal?
No. The SRPM07 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 SRPM07?
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 SRPM07?
20 mm. Any 20 mm strap fits.
