Questions
What movement is in the Seiko SRPJ91?
The SRPJ91 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 SRPJ91 have a sapphire crystal?
No. The SRPJ91 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 SRPJ91?
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 SRPJ91?
22 mm. Any 22 mm strap fits.
