Questions
Is there a Japanese version of the Seiko SBSA281?
The Japanese Seiko site lists no model with the same calibre, case and dial, so the SBSA281 has no Japanese domestic twin in the current lineup.
What movement is in the Seiko SBSA281?
The SBSA281 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 SBSA281 have a sapphire crystal?
No. The SBSA281 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 SBSA281?
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 SBSA281?
22 mm. Any 22 mm strap fits.
