From Silent to Sound - Reconstructive Restoration of Antique Repeater Pocket Watch Step Three: Restoration of Timing Function 1. Inlaid gem bearing Find a gem bearing and install it (see 30-31). 2. The breakage of the machined chronograph seconds axis is related to the explosion of the seconds axis gem. Imagine that the pocket watch is hit hard and the hands are compressed, causing the seconds axis to push upward, and the seconds axis and the gems are damaged at the same time. When re-turning a chronograph second shaft, you must first accurately measure the size (see 32). Because the chronograph second wheel is almost at the end of the power, the force pushing it is very small. What you need to pay attention to is how to reduce friction from the structure. For example, leaving a step at the beginning of the shaft (see 32), so that the area of ​​the axial contact with the gemstone is as small as possible (see 33). From Silent to Sound - Reconstructive Restoration of an Antique Repeater Pocket Watch 3: Making a Chronograph Return Spring The chronograph return spring is the source of power for returning the chronograph function to zero, so it requires high elasticity. I used a high carbon steel saw blade to make the return spring (see 35). Since the original parts have been lost, I have a lot of room for my own imagination. I decided to make it the same style as the homing arm, also in the shape of a snake. In order to be of the same grade as other parts, I also chamfered and polished the return spring (see 36-38). After polishing, it can be installed (see 39). After restoring the travel time and chronograph functions, the watch got energy from the energy key like Optimus Prime and regained life. Step 4: Repair the two-question function. The effect before rust removal and polishing (see 40), and the effect after rust removal and polishing (see 41). Step 5: Customize blue steel hands for the dial. The material is still high carbon steel. My new attempt this time is to grind and chamfer the hands (see 42-43). The needles made this time are different from the previous ones, not only because they are chamfered, but also because this watch is a repeater watch with complex repeater components hidden under the dial, so the pins are also very long, and the pins need to be turned out with a lathe. Then a bluing process is used to form an oxidation-resistant layer on the surface of the needle (see 44-46). I used my imagination to make the tail of the chronograph second hand into a small crescent. I like it very much. Completed article: In the dead of night, I lay quietly on the bed alone, without turning on the light, and gently wound it. Put it to your ear and listen to the tick, tick, tick sound it makes. From time to time, I turn the lever and listen to the ancient sound from the era before electric light was invented. This ancient sound is still so crisp. Where were the people who listened to this voice like me back then? Which country are you from? With my mind racing, I fell asleep unknowingly...
