With 300 meters of
link water resistance and a screw-down
link crown, the D-1 has all of the elements you'd expect for a modern dive watch, including a matte-black ceramic bezel insert with luminous markings (and 120-click action), tons of lume, an exceedingly legible handset, and no-date display. The 120-click bezel is
link nicely aligned, not too heavy in use, and very easy to operate (even while wearing gloves).
