While holding the Rolex in your hand, turn the crown counterclockwise towards you. The winding crown will begin to release from the screws within the watch. Once the winding crown has completely detached from the screws, it will pop out and go into the winding position. With the winding crown popped out and into the winding position, you will turn the winding crown clockwise or forward for 35 to 40 rotations.
You should begin to feel the tension and hear a light clicking sound. This is how you know the gears inside the watch are winding. After turning the winding crown for approximately 40 rotations, you can now set the date on your Rolex. To do this, you will use the winding crown once again. Pull the winding crown gently, and it will pop slightly out.
This places the winding crown in the correct position to change the date. Turn the knob of the crown clockwise away from you as many rotations as you need to get to the correct date. Using the winding crown again, gently pull the winding crown once more, and you will feel it pop out to the position in which you can set the time on your Rolex.
Set the time by turning the knob of the crown clockwise away from you. You will see the hands on the clock begin to turn. Keep turning the crown until you have reached the correct time.
Once you have set your time and date for your Rolex, you will need to close the crown. To do this, you will simply push the crown until it clicks back into place. Keeping the crown closed is important because it will prevent dirt, dust, and water from entering your watch. You will need to screw the crown back into place.
Just a few turns to the crown clockwise or away from you will screw the crown back into place. Instead, the winding crown of the watch is already in position for you to wind. To wind a watch without a screw-down crown, you will simply begin turning the knob of the crown clockwise away from you. This will begin the winding process of the gears within the watch. You should turn the knob between 30 and 40 times on the watch.
The invention around of a self-winding pocket watch, whose winding was carried out via a rotor system with an oscil-lating weight that captured the energy generated by the movements of the wearer, is credited to Abraham-Louis Perrelet or Hubert Sarton experts differ on this subject. But the movements of the wearer had little influence on.
In attempts to improve the winding yield, systems using alternat-ing movements were developed. Among them, a system in which the path of the weight was limited by stops which it struck and from which it rebounded to amplify the back-and-forth motion.
It was such a system that an English watchmaker named John Harwood transposed for the first time to a wristwatch in Although it was efficient for pocket watches, the winding based on stops was too rough and therefore inappropriate for a wristwatch. After years of research and devel-opment to achieve a reliable and efficient result, Rolex perfected the Perpetual rotor in The result fulfilled all hopes: as soon as it was introduced, the Perpetual rotor enjoyed a phenomenal success and became the symbol of watchmaking excellence.
Once the patents expired and the invention fell into the public domain, it was adopted by the entire watchmaking industry, which quickly made the principle its own. For more than eight decades already, and for a very long time to come. Several parameters are critical for the rotor to yield the full measure of its winding power. First, the oscillating weight must be as heavy as possible. To accomplish this, Rolex generally uses a particularly dense tungsten alloy, thus ensuring a rotor with excellent dynamic properties in spite of its small dimensions.
Next, the center of gravity of the weight must be as peripheral as possible and its motion must never be impeded by the movement or the case.
Finally, the watch must be wound as quickly as possible, without being over-wound, because on an active wearer — a sportsperson, for example — the clutch system preventing over-winding of the spring would be too often brought into play. If you consider that there is a factor of between the movements made by a wearer who is jogging and those of a wearer sitting at his desk all day, it is easy to imagine the delicate balance that must be achieved so that the winding mechanism remains reliable in all circumstances.
At the Bienne site, the various components of the self-winding system are manufactured and assembled. Each one is first shaped, then machined.
Each is checked, controlled, inspected. Because every little detail is important, in Bienne as everywhere in the company, a taste for beauty and a passion for detail motivate each workshop. Our number one goal is to make you so satisfied with your purchase that we get the honour of helping you with your next watch purchase.
We will guide you through your whole experience with us. Our goal is to make you feel safe throughout the purchase process. Therefore, we carefully check all our timepieces to ensure their authenticity and that everything is in its order.
