Join us for another installment of our “How To” series. Today, we’re delving into the intricacies of setting the iconic Rolex Sea-Dweller, a watch renowned for its robust construction, exceptional water resistance, and, of course, that distinctive helium escape valve – the button on the side that often sparks curiosity. We’ll cover everything from the basics of time setting to understanding the nuances of the different Sea-Dweller models, including the highly sought-after Rolex Sea-Dweller 50th Anniversary edition. But first, let's address the elephant in the room: that intriguing button.
The Helium Escape Valve: More Than Just a Button
That seemingly innocuous button on the side of your Rolex Sea-Dweller is no mere aesthetic flourish; it's a crucial component enabling the watch to withstand the extreme pressures encountered during saturation diving. During deep-sea dives, divers often utilize specialized saturation chambers filled with a helium-oxygen mix. Helium, being a smaller molecule than air, can penetrate the watch's case under pressure. As the diver ascends, the helium expands, potentially causing damage to the watch crystal or movement. The helium escape valve allows this expanded helium to escape safely, preventing potentially catastrophic damage. It's a testament to Rolex's unwavering commitment to functionality and performance in extreme environments. This valve is not something you'll typically need to interact with during everyday use. It's designed to be activated only under specific, controlled conditions by professional divers.
Setting the Time on Your Rolex Sea-Dweller
Now, let's get down to the practicalities: setting the time on your Rolex Sea-Dweller. The process is largely similar across the various models, although the specific aesthetics might differ slightly.
1. Unscrewing the Crown: Locate the crown (the winding knob) at the 3 o'clock position. Carefully unscrew it by turning it counter-clockwise. You'll feel a slight resistance as you unscrew it; this is normal. Do not force it.
2. Pulling Out the Crown: Once the crown is unscrewed, pull it out. There are typically three positions:
* Position 1 (Slightly Pulled Out): This position allows you to adjust the date. Turn the crown clockwise to advance the date.
* Position 2 (Pulled Out Further): This position allows you to set the time. Turn the crown clockwise to set the time. Move the hands slowly and precisely.
* Position 3 (Fully Pulled Out – Usually not necessary): In some older models, this position might be needed for quick setting of the date, but this is generally not required in newer models.
3. Setting the Time and Date: Once you've set the time and date to your desired accuracy, gently push the crown back into its original position. Screw the crown back in tightly, ensuring it's fully secured. This is crucial for maintaining the watch's water resistance.
