From the inventors that brought you the world's first quartz watch, and the first chronograph with a vertical clutch, comes the most accurate mechanical dive watch available. The Marinemaster, affectionately referred to as the "Tuna Can", is the perfect dive watch. The black DLC coated titanium case is a unique shape that protects the single locking crown and prevents the bezel from accidental trauma and damage. The dial is black with white luminous hands and indices, a date window at 4:30, and a power reserve meter at 8:30. The dial is framed with a black hard coated bezel with white Arabic numerals, and a luminous triangle at 12. This instrument is held on your wrist with an extremely comfortable articulated rubber strap. Arguably the finest strap of this kind that I have seen. However, the true beauty of this watch lies within its mechatronic movement. The Spring Drive movement replaces a traditional escapement with a quartz oscillator. A unique Tri-Synchro regulator breaks the movement magnetically and allows the hands to move smoothly, and silently around the picturesque dial. A locking crown allows this piece to remain water resistant to 600m. One available. Retail on this item is $4,200.
