IN THE FIELD WITH ROLEX WATCHES
All Rolex wristwatches are waterproof to depths of at least 100 metres for Oyster Perpetual models, and 50 metres for Cellini models. Some Oyster watches can withstand depths of 1,220 or even 3,900 metres. To maintain your watch's waterproofness, the winding crown must be screwed down tightly to create a hermetic seal. When you reset the time, the date or other functions or wind the watch manually, it is extremely important to ensure that you have screwed down the winding crown until it cannot turn any further. After wearing your watch in the sea, it is important to rinse it with fresh water to remove any salt and sand deposits.
The Rolex Oyster Case, originally developed in 1926, is the first of its kind and has been providing excellent protection against shock so, you can be sure that your watch will function in the field, on the court and on the run.
Rolex watches have been time tested in the most extreme conditions imaginable. From the deepest oceans to the highest mountain peaks, in the sky and on the road and every single one is rigorously tested to ensure it will maintain optimal performance.
