The Rolex Submariner, a legendary dive watch synonymous with precision and reliability, can sometimes exhibit unexpected behavior. One common issue reported by owners is the watch running fast. While Rolex is renowned for its accuracy, even these meticulously crafted timepieces can experience variations in timekeeping. Understanding the reasons behind a fast-running Submariner and the methods to address this issue is crucial for maintaining its accuracy and preserving its value. This article will delve into the intricacies of a fast-running Rolex Submariner, exploring potential causes, adjustment methods, and preventative measures.
Rolex Running Fast: Understanding the Mechanics
A mechanical watch, like the Rolex Submariner, relies on the intricate interplay of gears, springs, and a precisely regulated escapement mechanism. The mainspring, when wound, stores energy that's gradually released, powering the movement. The escapement controls the release of this energy, regulating the rate at which the balance wheel oscillates. This oscillation, measured in vibrations per hour (vph), determines the accuracy of the watch. A Rolex Submariner typically oscillates at 28,800 vph.
Several factors can influence the rate at which a mechanical watch runs. These include:
* Wear and Tear: Over time, the components of the movement can wear down, leading to variations in timekeeping. Lubrication plays a crucial role; insufficient or degraded lubrication can increase friction, affecting the balance wheel's oscillation and potentially causing the watch to run fast.
* Temperature Fluctuations: Temperature changes can affect the expansion and contraction of the balance wheel and other components. Extreme temperature variations can lead to significant timekeeping discrepancies.
* Magnetic Fields: Exposure to strong magnetic fields can disrupt the delicate magnetic properties of the balance spring (hairspring), causing the watch to run fast or slow.
* Shock: Impacts or sudden shocks can affect the delicate balance of the movement, potentially leading to inaccuracies.
* Positional Variations: The position of the watch can also impact its timekeeping. Gravity can influence the balance wheel's oscillation, leading to variations depending on whether the watch is crown-up, crown-down, or dial-up.
* Manufacturing Tolerances: Even with Rolex's exacting standards, slight manufacturing variations can exist between individual watches, leading to minor differences in timekeeping.
* Winding Technique: While not a direct cause, aggressive winding can sometimes introduce stress on the movement, potentially affecting its performance in the long run.
Rolex Submariner Running Fast: Adjustment and Solutions
When a Rolex Submariner runs fast, it requires professional attention. Attempting to adjust the watch yourself can cause irreversible damage to the delicate movement. The correct approach involves taking the watch to an authorized Rolex service center or a qualified watchmaker specializing in Rolex repairs.
The process typically involves:
* Diagnosis: A skilled watchmaker will thoroughly inspect the movement, identifying the cause of the fast running. This may involve using specialized tools to measure the rate of oscillation and assess the overall health of the movement.
* Regulation: If the cause is simply a slight imbalance in the regulation, the watchmaker will adjust the timing screws on the balance wheel. This is a precise procedure requiring expertise and specialized tools. The goal is to fine-tune the oscillation rate to bring the watch within the acceptable range of accuracy specified by Rolex.
