Questions
What is the Japanese version of the Seiko SRPH33?
In Japan the SRPH33 is sold as the SBSA143: the same 4R36 calibre, the same 39.4 mm case and 100 m water resistance. Only the reference differs by market.
What movement is in the Seiko SRPH33?
The SRPH33 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 SRPH33 have a sapphire crystal?
No. The SRPH33 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 SRPH33?
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 SRPH33?
20 mm. Any 20 mm strap fits.
