Questions
What movement is in the Seiko SSK027?
The SSK027 runs on the Seiko 4R34, an automatic movement that can also be wound by hand. See the 4R34 page for its specs and every watch built on it.
Does the Seiko SSK027 have a sapphire crystal?
No. The SSK027 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 SSK027?
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 SSK027?
22 mm. Any 22 mm strap fits.
