Skeleton watches — which show off the watchmaker’s art by means of removing much of a watch’s movement so that only its “bare bones” remains, and giving us a glimpse of it through a transparent dial — were not as much of a presence at this year’s SIHH as in previous years. However, the few skeletonized timepieces (also referred to as “openworked”) that did make their debut here were quite notable. (Vacheron Constantin, in fact, devoted many of its new releases to openworked styles; you’ll see more on that tomorrow.) Here are three that I found to be particularly interesting (a fourth, from Piaget, which we discovered in a brand video, unfortunately did not have photos available immediately; stay tuned for that one.)
