Tudor Dive Watches Origins

It was in 1954 that the world was introduced to the first TUDOR divers’ watch. That watch was the TUDOR Oyster Prince Submariner – reference 7922. It was an automatic (self-winding) watch and the first in their collection with guaranteed water resistancy. To achieve that it’s case featured a screw-down back and a crown whose water resistancy was guaranteed to a depth of 100 metres.

The FIRST Tudor diver's watch - the Oyster Prince Submariner ref 7922

It featured over-sized, luminous hour markers and hands for easy reading at depth underwater. It also included the essential dive time bezel graduated in 5-minute intervals. On the dial were printed the words “OYSTER PRINCE” under the Tudor logo and “100 m = 330 ft”, “SUBMARINER”, “ROTOR”, “SELF-WINDING” on the bottom four lines.


Rolex origins since 1926

The Tudor brand was established in 1926 when Hans Wilsdorf (Rolex founder) said:

For some years now, I have been considering the idea of making a watch that our agents could sell at a more modest price than our Rolex watches, and yet one that would attain the standard of dependability for which Rolex is famous. I decided to form a separate company, with the object of making and marketing this new watch. It is called the TUDOR watch company.


and that’s why many of the older Tudor watches bear the Rolex logo and brand name on their cases, case-backs and bracelet buckles. So now you know why every watch collector should own a TUDOR watch, let’s go shopping …

Tudor Black Bay

The current Black Bay models are the culmination of over Sixty years of TUDOR diving experiences. A depth of experience and history distilled into one iconic watch. The new Black Bay is powered by an in-house mechanical automatic (self-winding) movement.

The origins of the Black Bay date back to 1954 and the launch of reference Oyster Prince Submariner ref-7922 (shown above). This watch heralded the beginning of a long line of ergonomic, legible, accurate and robust divers’ watches. Importantly, a feature sometimes overlooked by other luxury brands – the Black Bay is still and always has been an understated, functional and reliable underwater tool.
