The Sea Auto 30 is a 42mm automatic dive watch that updates the quartz Sea Quartz 30 made famous on Magnum P.I. It runs a Miyota 9015 high-beat movement with a 42-hour power reserve, a smooth sweeping seconds hand and a slim case profile. A solid sapphire crystal, a unidirectional glass bezel, Super-LumiNova lume and 300m water resistance with a screw-down crown and caseback make it a genuine dive-capable watch. It suits buyers who want vintage diver looks with mechanical internals; against quartz rivals it trades battery-free convenience for winding and service, and against premium Swiss divers it gives similar specs at a lower tier of finishing.

The Sea Auto 30 is a 42mm automatic diver watch. It is inspired by the Sea Quartz 30 worn in Magnum P.I. and uses a classic diver case based on the original 1980s silhouette. The profile is slim, and the seconds hand has a smooth sweep.
It runs on a Japanese Miyota 9015 automatic movement, which is slim and high-beat and has a 42-hour power reserve. A sapphire crystal sits slightly recessed below the steel rim of the bezel. The unidirectional glass bezel is used to track elapsed time.
The crown and caseback are screw-down, and the watch is water resistant to 300 meters. Super-LumiNova lume gives visibility in low light. The caseback is finely engraved with an Orca whale, a Pacific Coast icon.
