Questions
What is the Japanese version of the Seiko SRPK65?
In Japan the SRPK65 is sold as the SBSA243: 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 SRPK65?
The SRPK65 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 SRPK65 have a sapphire crystal?
No. The SRPK65 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 SRPK65?
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 SRPK65?
22 mm. Any 22 mm strap fits.
