The Rolex Submariner, a legendary dive watch synonymous with robustness and precision, is a coveted timepiece for many. Its iconic design and unparalleled reliability have cemented its place in horological history. However, even the most robust watches can encounter issues, and one common concern among Submariner owners is a malfunctioning seconds hand – specifically, a seconds hand that refuses to move after the watch has been unworn for a period. This article explores the potential causes of this problem, offering insights into troubleshooting and repair options, while also touching upon the broader market for pre-owned Rolex Submariners.
The scenario presented – a Rolex Datejust (not a Submariner, a crucial distinction) experiencing a stationary seconds hand after periods of inactivity – highlights a common problem that can affect various Rolex models, including the Submariner. While the initial description refers to a Datejust, the principles discussed here are largely applicable to the Submariner as well. The fact that the seconds hand stops moving after the watch has been unworn suggests a problem with the power reserve, the mainspring, or the escapement mechanism. Let's delve deeper into the potential causes.
Potential Causes of a Stationary Seconds Hand:
1. Insufficient Power Reserve: The most straightforward explanation is that the watch's mainspring, which stores energy, hasn't been fully wound. Rolex watches, even automatic ones, require a certain amount of winding to maintain their power reserve. If the watch hasn't been worn for an extended period, the mainspring may have completely unwound, resulting in a stopped seconds hand. This is easily remedied by manually winding the crown. If the seconds hand still doesn't move after several full rotations of the crown, further investigation is necessary.
2. Mainspring Issues: A more serious problem could be a weakened or broken mainspring. Over time, the mainspring can lose its elasticity, reducing its ability to store and release energy effectively. A broken mainspring is a complete failure and requires professional repair. This is a common issue in older watches or those that haven't been serviced regularly.
3. Escapement Problems: The escapement is the heart of a mechanical watch, regulating the release of energy from the mainspring. It's a complex mechanism comprising several components, including the escape wheel, pallet fork, and balance wheel. Any malfunction within the escapement, such as a damaged pallet jewel, a worn escape wheel, or a problem with the balance wheel, can cause the seconds hand to stop. This requires expert diagnosis and repair.
4. Lubrication Issues: Mechanical watches rely on precise lubrication to minimize friction and ensure smooth operation. Over time, the lubricating oil can dry out or become contaminated, leading to increased friction and potential malfunctions. A lack of lubrication in the escapement can significantly impede its function, causing the seconds hand to stop.
5. Other Potential Problems: Less common but still possible causes include issues with the winding mechanism, the gear train, or even a foreign object obstructing the movement.
Troubleshooting and Repair:
Before considering expensive repairs, try the following:
* Wind the watch fully: Give the crown several full rotations to ensure the mainspring is fully wound.
* Gently shake the watch: A light shake can sometimes dislodge any minor obstructions within the movement.
