- Screw-down crown at four o'clock, shielded by the case profile
- Silicone strap keeps the weight down and rinses clean after seawater

Watch Brands: Seiko
Seiko makes its own movements, its own hairsprings and its own luminous compound, and it does so across a range that runs from a $150 automatic to Grand Seiko. No other brand covers that span in-house.
