The Rolex Submariner is an iconic timepiece known for its precision, durability, and water-resistant capabilities. As a luxury dive watch, it is designed to withstand the rigors of underwater exploration while keeping accurate time. However, some Submariner owners may encounter the frustrating issue of their watch stopping unexpectedly. In this blog post, we will explore common reasons why a Rolex Submariner may stop and provide troubleshooting tips to ensure your watch maintains its timeless reliability.
1. Insufficient Power Reserve
The most common reason for a Rolex Submariner to stop is an insufficient power reserve. Automatic watches like the Submariner rely on the movement of the wearer’s wrist to power the watch. When the watch is not worn for an extended period or is not moved enough, the mainspring inside the watch can unwind completely, causing it to stop.
Troubleshooting Tip: To keep your Submariner running smoothly, wear it regularly or invest in a watch winder. A watch winder mimics the movement of your wrist when the watch is not in use, ensuring the mainspring remains wound and the watch stays powered.
2. Magnetic Interference

Rolex Submariners are built to be antimagnetic to a certain extent, but they can still be affected by strong magnetic fields. Magnetic interference can disrupt the delicate components within the watch movement, leading to irregular timekeeping or even complete stoppage.
Troubleshooting Tip: Avoid placing your Submariner near strong magnetic sources such as speakers, electronic devices, or magnetic closures. If you suspect your watch has been exposed to a strong magnetic field, have it demagnetized by a professional watchmaker.
3. Water Damage
While the Rolex Submariner is designed to be water-resistant, exposure to water beyond its rated depth can lead to water ingress, damaging the internal components. Water damage can cause the movement to seize or stop working altogether.
Troubleshooting Tip: Ensure you are aware of the water resistance rating of your specific Submariner model and avoid using it beyond the recommended depth. If your watch has come into contact with water, immediately take it to an authorized Rolex service center for inspection and maintenance.
4. Dirt and Debris
Dirt, dust, and debris can find their way into the movement over time, hindering its proper functioning. Accumulation of these particles can lead to increased friction, affecting the watch’s accuracy and potentially causing it to stop.
Troubleshooting Tip: Regularly clean your Submariner’s exterior with a soft, lint-free cloth. To address internal dirt and debris, it is best to have your watch serviced by a professional watchmaker who can disassemble and clean the movement properly.
5. Worn or Damaged Components
As with any mechanical device, the components inside a Rolex Submariner can experience wear and tear over time. A worn or damaged gear, spring, or balance wheel can disrupt the movement and cause the watch to stop unexpectedly.
Troubleshooting Tip: If you notice any irregularities in your watch’s timekeeping or if it repeatedly stops, take it to an authorized Rolex service center for a thorough inspection. Skilled watchmakers can identify and replace worn or damaged components to restore your Submariner’s reliability.
6. Battery-Operated Counterfeit
If you own a Rolex Submariner with a quartz movement, a sudden stoppage may indicate that you have unknowingly purchased a counterfeit watch with a depleted battery.
Troubleshooting Tip: To ensure the authenticity of your Rolex Submariner, only purchase from authorized dealers. If you suspect you have a counterfeit watch, consult an authorized Rolex service center for verification.
Conclusion
The Rolex Submariner is an engineering marvel, combining luxury, precision, and durability in a single timepiece. If your Submariner keeps stopping, the issue is likely related to insufficient power reserve, magnetic interference, water damage, dirt and debris, worn components, or, in the case of a quartz movement, a depleted battery in counterfeit watches. By following the troubleshooting tips provided in this blog post and maintaining regular servicing, you can ensure your Submariner maintains its timeless reliability and continues to be a reliable companion for all your adventures, both above and below the surface. Remember, investing in the care of your Rolex Submariner is an investment in its longevity and the enjoyment it brings for years to come.
