The Rolex Submariner
As the Rolex Submariner celebrates its 50th anniversary, we can trace it roots back to the very first waterproof Rolex Oyster. However, the appearance of the model 6204 Submariner in 1954, signaled the dawn of what we have come to identify as the ultimate sports tool watch.

The Rolex 6204 was fitted with a Rolex caliber A296 semi-bubbleback automatic movement and was waterproof to 600 ft. This model was followed by the 6200 and the 6205.   cont'd
