Seiko Quartz Marine Master Limited Edition 1000M SBBN029 Men's Watch

The Marinemaster series is synonymous to security and precision as sensed in the pro-world. It embodies the very best of diving concepts Seiko experienced in 50 years. It pushes back the boundaries of diver technology with its two-layer case construction with the inner case structure made extra tough. The L-shaped gasket and the screw-down glass fixing ring make it absolutely resistant to helium. This is the kind pro-level saturation diving needs. To top that, ceramic enhances the strength of the outer shell against shocks and unintentional rotation of the bezel.
