The Rolex 3135 movement, a workhorse of the watchmaking world, is renowned for its reliability and precision. However, even experienced watchmakers can encounter challenges during assembly, particularly when setting the minute hand. This article addresses the common problem of a minute hand failing to sit correctly on a VS3135 movement (a common clone of the 3135) and provides a detailed guide to achieving precise minute hand alignment. We will explore various aspects of the 3135 movement, including its technical specifications, comparison with other movements, and the importance of proper hand fitting.
The Problem: Minute Hand Misalignment on a VS3135
The initial query highlights a frequent issue: the minute hand on a VS3135 movement refusing to seat correctly. This problem, while seemingly minor, can stem from several factors, including:
* Incorrect Hand Stacking: The order in which the hands are placed on the movement is crucial. The hour hand goes on first, followed by the minute hand, and finally the seconds hand. Improper stacking can lead to interference and prevent the minute hand from seating properly.
* Bent Minute Hand: A slightly bent minute hand can prevent it from fitting snugly onto the cannon pinion. Even a minute bend, invisible to the naked eye, can cause significant problems.
* Damaged Cannon Pinion: The cannon pinion, the component that connects the minute hand to the movement, might be damaged or have debris obstructing the hand's placement. A bent or damaged cannon pinion will result in an uneven fit and potential hand slippage.
* Incorrect Hand Selection: Using hands not specifically designed for the VS3135 movement can lead to incompatibility. The minute hand needs to have the correct dimensions and fit precisely onto the cannon pinion.
* Insufficient Pressure: Applying insufficient pressure when fitting the minute hand can result in an incomplete connection. The hand needs to be firmly seated to ensure proper function.
* Foreign Material: Dust, lint, or other foreign materials can accumulate on the cannon pinion, hindering the minute hand's proper seating.
Addressing the Issue: A Step-by-Step Guide
Before attempting any repairs, it's crucial to have the appropriate tools and a clean, well-lit workspace. A jeweler's loupe, a hand-setting tool, and a cleaning brush are essential.
1. Thorough Inspection: Begin by carefully inspecting the minute hand, cannon pinion, and surrounding components under magnification. Look for any bends, damage, or debris. Clean the cannon pinion thoroughly using a soft brush and compressed air.
2. Hand Verification: Ensure you are using the correct minute hand for the VS3135 movement. Using incorrect hands can lead to frustrating incompatibility issues.
3. Proper Hand Stacking: With the movement securely held in a movement holder, carefully place the hour hand onto its arbor first. Then, place the minute hand onto the cannon pinion, ensuring it is aligned correctly. Finally, fit the seconds hand.
4. Applying Pressure: Use a hand-setting tool to gently but firmly press the minute hand onto the cannon pinion. Avoid excessive force, as this can damage the hand or the cannon pinion. The hand should snap into place with a subtle click.
