How to adjust the speed of a mechanical watch?

　　How to adjust the speed of a mechanical watch? This is a question that many people want to understand. In fact, there is a regulator index inside the mechanical watch structure to adjust the speed, so how exactly do you adjust it? Let's take a look at the method introduced by Xiaoya below.

　　Method for adjusting the speed of a mechanical watch

　　The basic principle of adjusting the speed with the regulator index is to adjust the timekeeping speed of the watch by changing the active length of the hairspring. When the length of the hairspring is reduced, the unit time of hairspring contraction becomes smaller, the frequency becomes faster, and the watch will run faster, and vice versa.

　　Open the case back, nudge the regulator index slightly towards the "-" direction. Do not move it too much the first time, just a tiny bit, such as half a scale mark. Wait for a day to see how it performs. If it is not ideal, nudge it a bit more towards the "+" or "-" direction depending on the situation. You can repeat this process several times until it is properly adjusted.

　　When adjusting the watch, care must be taken to clearly distinguish which part is the regulator index. Another component fitted on the balance cock alongside the regulator index is the movable stud carrier, which is used to adjust the beat error. To adjust the speed, you should adjust the regulator index; the stud carrier must not be touched. They must be correctly identified and not confused. Additionally, hairsprings can be coiled clockwise or anti-clockwise, so you cannot determine whether you are adjusting faster or slower simply by pushing the regulator index clockwise or anti-clockwise; the adjustment must always be based on the change in active length.

　　Accuracy error standards for mechanical watches

　　(1) The accuracy of a watch varies depending on its movement type. Quartz watches replace the balance wheel of mechanical watches with a quartz oscillator, utilising its precise high-speed oscillation to keep time. Generally speaking, quartz watches have higher accuracy, with the Swiss standard being a monthly error within 15 seconds, and some high-precision movements can even achieve an annual error within a few seconds.

　　(2) Mechanical watches rely on internal mechanical components to control the steady and accurate timekeeping of the watch. These mechanical components are affected by gravity, ambient temperature, etc., which cause errors. Generally, the error of a mechanical watch is calculated daily, varying according to the movement model and manufacturing quality. Usually, a daily error within 30 seconds is considered normal. Some higher-precision movements, such as the Chronometer series, can achieve around 10 seconds.
