Nixon Regulus Expedition Navy Watch Re-engineered, re-designed, and ready for anything. The new Regulus Expedition has adventure-specific features like an altimeter, barometer, and compass, combined with a sleek-yet-rugged case design that can stand up to whatever you throw at it. A blazingly brilliant MCLD displays info in multiple modes, and the supple silicone band stays comfortable even on the longest treks. Item cannot be shipped to P.O. Boxes
