Questions
What is the Japanese version of the Seiko SRE023?
In Japan the SRE023 is sold as the SRRA011: the same 2R06 calibre, the same 32.0 mm case and 100 m water resistance. Only the reference differs by market.
What movement is in the Seiko SRE023?
The SRE023 runs on the Seiko 2R06, an automatic movement that can also be wound by hand. See the 2R06 page for its specs and every watch built on it.
Does the Seiko SRE023 have a sapphire crystal?
No. The SRE023 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 SRE023?
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 SRE023?
15 mm. Any 15 mm strap fits.
