The Art of Openworked Movements – A Case Study with Vaucher

Skeleton Watches, Technical Perspective

Recently we brought you a detailed look at Vaucher, one of the most prominent high-grade mechanical makers for third parties in the watch industry (read our article here). We went back to the Val-de-Travers to take a look at how the movement manufacturer produces openworked movements, including their own calibre 5401.

The creation of openworked or skeleton watches, the art of playing with transparency aims at revealing the quintessence of the movement, allowing its wearer to admire its intricacies. When crafting an openworked/skeleton movement, the plate, bridges and other components such as the barrel cover are hollowed out and then carved to the bare essentials to reveal the inner workings that make it tick. It then requires complementary skills, those of master craftsmen to sublimate the movement with time-consuming finishing and decoration operations.

Case in point, the Vaucher calibre 5401 is available in traditional and openworked versions. The Caliber 5401 is an extra flat (2.6 mm) micro-rotor automatic movement, 13 ’’’ ¼ (30.00 mm) in diameter. It runs at 21,600 vibrations per hour with a 48h power reserve. It features just under 200 parts. ... -skeleton/
