This will definitely be affected, especially for mechanical watches. They contain many small moving parts. Too much strenuous exercise can cause the watch's small movement parts to run unusually quietly, so try to avoid doing this during strenuous exercise. .With a watch.
The main reasons that affect the timing accuracy of the watch are:
1. The influence of swing
The tightness of the spring will directly affect the balance wheel. The size of the amplitude therefore also affects the isochronous performance of the watch. So-called "isochrony" refers to a phenomenon where the amplitude of the oscillating object does not affect the period of vibration. However, the watch's balance and hairspring system does not oscillate freely. It frequently bumps and hits exhaust components. This is a combined “forced” vibration state.+ free", so it must be affected by the exhaust system. The size of the impulse torque determines the size of the oscillation and also determines the time required for their relationship. Of course, the shorter the time, the better.
2. The impact of position changes
The main position changes are changes of planes and vertical planes. There are 2 planes (surface up and surface down), and only 3 elevations are. account. (crown down, crown left, crown up), crown right will not occur when worn normally, so there are a total of 5 positions. The change in position first causes a change in the friction surface of the balance shaft pin. Second, the imbalance of the pendulum becomes more obvious and greater under the action of gravity. Additional torque acts on the rapid swing. pendulum. The gravid effecttation of the balance and hairspring on the wheel and hairspring means that the oscillation cycle of the balance and hairspring system of the watch is affected by different sizes at each position.
3. The influence of the hairspring speed clip
Most watches have hairspring speed clips. The function of the speed clip is to easily correct the travel time accuracy. difference between the speed clip and the hairspring, There is a gap between them, also called "swing gap". Its existence greatly destroys the isochronism of the watch and also increases the position error of the watch.
4. The impact of temperature changes
Temperature changes will also modify the geometric dimensions of the balance and hairspring. Every small change in these key components will directly affect the oscillation cycle and. Temperature will also change the viscosity of the watch oil, thus changing the transmissionof torque and the swing of the watch gear train.
5. Influence of the magnetic field
Many parts of the watch movement are made of steel, so they are easily magnetized. The nickel-based hairspring is also weakly magnetic, and the watch will be. affected by an external magnetic field. If the parts are magnetized, the swing cycle of the balance wheel will be greatly disrupted by the magnetic force and the watch will generally run very fast.
6. The impact of shock and vibration
Severe shock and vibration also have an impact on the vibration cycle of the balance wheel, particularly for watches with low amplitude or low frequency. In case of severe shock and vibration, if the balance shaft tenon or spring has been damaged, it will inevitably lead to time failure in the watch.
7. Processing tolerances of watch movement parts
Watches arent the most precise and smallest mechanical devices. The difference range can be as small as 1/1000mm. Part processing error is also one of the important reasons for watch time error.
8. Other factors
The main reason is that the watch case is not tightly closed, so changes in humidity and air pressure will affect the timing accuracy of the watch
