Tudor Submariner 89190

5953 Hydronaut 89190 c. 1999 Box The Tudor Hydronaut is a little-known reference - not quite a Submariner, not quite a dress watch. It's probably the closest thing that Tudor has to a Yacht-Master; a dive watch with a quirkier design. The sunburst silver dial, 15-minute markers on the bezel, and arrow hands certainly make it stand out.
