Introduction

Watches may seem like a small accessory on the wrist, but they are complex machines that require attention and care to keep them working properly. If you are a watch enthusiast or a professional watchmaker, you know the troubles that come with watch repair. One of the most common issues is the search for amplitude in the mainspring barrel. In this article, we will explore the Hamilton 917 wristwatch project and discover a technique to troubleshoot low amplitude and improve your watch repair skills.

The Hamilton 917 Wristwatch Project

The Hamilton 917 wristwatch project is a classic timepiece that requires delicate attention to keep it working. The aim of this project is to not only troubleshoot common issues associated with watch repair but also to develop a process for inspection and service work.

Troubleshooting Low Amplitude

In the Hamilton 917 wristwatch project, the amplitude of the watch initially had a range of 230 degrees in flat positions, with a 40-degree drop in hanging positions. The goal was to find at least another 80 degrees of amplitude to hit the minimum regulation requirement of 270 degrees. When troubleshooting low amplitude, it is essential to start with the mainspring barrel as it is the power source for the watch.

Checking the End and Side Shake of Arbor

The end and side shake of the arbor should be checked to ensure that the barrel does not turn at an angle, causing friction or inefficiency in power transfer. The end shake refers to the play of the arbor in the jewel holes, while the side shake concerns the movement of the arbor in the plate holes.

Checking for Out of Round Arbor Holes

Out of round arbor holes can cause the barrel to come in contact with the bridge or plate and lower the available power, resulting in low amplitude. Check for out-of-round holes with a pivot gauge, which measures the diameter of each pivot. If a pivot gauge is not available, a jeweler’s loupe can be used to inspect the shape of the holes.

The Importance of the Mainspring

The mainspring is an essential component of the watch that stores and releases energy, creating the movement of the watch. If the mainspring is not in good condition, it can cause lower amplitude. Inspect the mainspring for wear or damage, and if necessary, replace it with a new one.

Finding the Loose Impulse Jewel

In the Hamilton 917 wristwatch project, the loose impulse jewel prevented the balance wheel from operating, resulting in low amplitude. The impulse jewel is responsible for transferring energy from the escape wheel to the balance wheel. In this project, the impulse jewel was reset, resulting in higher amplitude.

Conclusion

Watch repair requires skill and careful attention to detail. Troubleshooting low amplitude in the mainspring barrel is a common issue that can be resolved by inspecting the end and side shake of the arbor and checking for out-of-round arbor holes. It is also essential to inspect the mainspring and the impulse jewel for wear or damage. By following these steps and utilizing the simple technique outlined in the Hamilton 917 project, you can improve your watch repair skills and leverage your amplitude.
