OF A CONCEPT
Crowned with success
A little masterpiece of technical prowess, the winding crown is made up of about 10 parts, and is screwed onto a tube that forms an integral part of the watch case. This is how Rolex, for the first time in the history of watchmaking, crafted a water-resistant winding crown - the interface between the protected, sealed world inside the watch and the wet, wild world outside.
The crown not only hermetically seals the case – it also provides access to the watch’s key functions. The crown can be pulled out to adjust the time, date, day or time zone, or to wind the watch manually if need be. Rolex Twinlock and Triplock winding crowns use two or three sealed zones inside the tube to ensure watertight security akin to a submarine’s hatch.
