Many Rolex owners, proud possessors of some of the world's most prestigious timepieces, might find themselves facing a frustrating situation: their Rolex stops ticking when not worn. This isn't necessarily a sign of a major malfunction, but understanding the reasons why this happens is crucial to ensuring the longevity and accuracy of your investment. This article will delve into the reasons behind a stopped Rolex, addressing common concerns such as insufficient power reserve, potential mechanical issues, and what steps to take if your Rolex isn't keeping accurate time. We'll explore the various scenarios, from a simple power reserve test to more complex mechanical problems that require professional attention.
Understanding Power Reserve: The Heart of the Matter
The most common reason a Rolex stops when not worn is simply a depleted power reserve. Unlike quartz watches powered by batteries, mechanical Rolex watches rely on the energy stored in a mainspring. This spring is wound by the movement of the crown, and its unwinding powers the intricate mechanism that drives the hands. The power reserve, which is the length of time the watch can run on a single winding, varies depending on the specific Rolex model and movement. Generally, a Rolex will have a power reserve of between 38 and 70 hours. This means that after fully winding the watch, it will continue to run for that duration before stopping.
Testing Your Rolex's Power Reserve: A Simple Diagnostic
To accurately check your Rolex's power reserve, follow these steps:
1. Fully wind the watch: This is crucial. Using the crown, carefully wind the watch completely. The number of rotations required varies by model, but a good rule of thumb is around 40 complete turns. You'll feel resistance when the mainspring is fully wound. Avoid over-winding, as this can damage the movement.
2. Set the watch down: Place the watch face up in a safe location. Avoid any significant shocks or vibrations.
3. Observe and record: Note the exact time you set the watch down. Let it run undisturbed until it stops completely. Record the exact time it stops.
4. Calculate the power reserve: Subtract the starting time from the stopping time. The result is the actual power reserve of your watch. If it's significantly less than the expected power reserve for your model, it could indicate a problem.
Why Your Rolex Might Stop: Beyond Power Reserve
While a depleted power reserve is the most frequent cause of a Rolex stopping, other issues can also be at play. Let's explore some of these:
* Mechanical Issues: As intricate mechanical devices, Rolexes are susceptible to mechanical problems. These can include:
* Worn or damaged parts: Over time, components within the movement can wear down, leading to reduced efficiency and potentially stopping the watch. This is especially true for older watches or those that have experienced significant shocks.
* Lubrication problems: The internal components of a mechanical watch require regular lubrication to function smoothly. Insufficient lubrication or the use of inappropriate lubricants can lead to friction, reduced efficiency, and ultimately, the watch stopping.
* Dust or debris: Dust and debris can enter the movement, interfering with the delicate mechanisms and causing the watch to malfunction.
* Magnetization: Exposure to strong magnetic fields can affect the accuracy and functionality of a mechanical watch, potentially causing it to stop.
* Incorrect Setting: While less common, an incorrect setting of the date or time, particularly around midnight, can sometimes cause temporary issues.
* Impact Damage: A significant impact or drop can damage internal components, leading to the watch stopping.
