One of the most popular movements in the world of watchmaking is the OPENHEART PTS-3JZOE Tourbillon movement.
However, there are certain engineering mistakes that can be made in panel sizing that must be carefully considered when using this movement to make a watch.
1.There are several key points that must be considered when using the PTS-3JZoe tourbillon movement to make a watch. Firstly, if using a single layer panel that is 0.4mm thick, there are two scenarios to consider.
In scene A, the distance between the balance wheel and the dial center hole wall (on one side) must be less than 0.25mm. During the assembly process, the watchmaker must be extremely careful to avoid the balance wheel touching the dial center hole wall, which could cause the watch to stop.
In scene B, where the distance between the balance wheel and the dial center hole wall (on one side) is greater than or equal to 0.25mm, the technical requirements for the watchmaker during the assembly process are relatively low.
2.Secondly, if using a double panel that is either 0.4mm+0.25mm=0.7mm or 0.4mm+0.4mm=0.8mm, the upper and lower layer plates must be assembled together. However, since the center hole cannot be coincident, the balance wheel must be at least 0.3mm away from the dial center hole wall (on one side), otherwise the watch is prone to stopping.
3.Finally, when the panel is composed of multiple panels, the center hole offset data is larger. This means that both the tolerance of the panel control center hole and the distance between the balance wheel and the center hole wall of the dial (on one side) are larger, possibly exceeding 0.4mm.
In general, it is important to ensure that the assembly process is easy for the watchmaker and that the watch keeps accurate time without stopping. At the same time, it is also important to ensure that the balance wheel distance from the dial center hole wall is not too large, to maintain an aesthetically pleasing appearance.
Precision in watchmaking is crucial, and any mistake can have a significant impact on the watch's performance.
Therefore, continuous innovation is an absolute principle in the world of watchmaking.
