Produced by Bernhardt of High point, North Carolina exclusively for Wilson Combat, the Binnacle Diver is robust and resilient. The water-tight construction and durable automatic movement make the Binnacle Diver an excellent choice. Beneath the signature "tooth dial" beats a Miyota 8215 movement designed by the Citizen Corporation of Japan. An automatic movement made for reliability and years of use and abuse, no battery needed, only the centrifugal movement of your wrist. The steel case and crown are signed and entirely screwed in. The Binnacle Diver provides water resistance to 200 meters (600 feet).The sapphire crystal is virtually scratch proof.
