Questions
What movement is in the Seiko SBSA277?
The SBSA277 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 SBSA277 have a sapphire crystal?
No. The SBSA277 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 SBSA277?
100 m (10 bar). That covers swimming and snorkelling; it is not a certified diver's watch unless Seiko says so.
