In watchmaking, what indicates that manual skeletonization has been properly executed?

In watchmaking, the proper execution of manual skeletonization is indicated by the interior angles being perfectly sharp. This technique involves the careful removal of material from the movement's mainplate and bridges to create an aesthetically pleasing view of the inner workings of the watch. Sharp interior angles demonstrate a high level of precision and craftsmanship, reflecting the skill of the watchmaker. Such details are crucial because, in watchmaking, even slight imperfections can compromise not only the visual appeal but also the structural integrity of the watch.

When the interior angles are sharp, it signifies that the skeletonization process has been done meticulously, allowing for a more refined and elegant appearance, which is a hallmark of quality watchmaking. Conversely, rounded angles may suggest a lack of precision or attention to detail, while complexity in design does not guarantee quality in execution. The reduction in weight, although an effect of skeletonization, is not a direct indicator of the quality of the angles or the skill involved in the skeletonization process itself.
