Questions
What is the Japanese version of the Seiko SRPK29?
In Japan the SRPK29 is sold as the SBSA225: 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 SRPK29?
The SRPK29 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 SRPK29 have a sapphire crystal?
No. The SRPK29 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 SRPK29?
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 SRPK29?
20 mm. Any 20 mm strap fits.
