This looks like an exercise in “odd design” but I suppose there are a few interesting innovations here. This was made by the same bloke, Jean-FranÃ§ois Ruchonnet, who created the TAG Heuer Monaco V4 Concept Watch. I’m not quite understanding this whole thing, but here’s a quick discussion:
Winding the watch and setting the hour and minutes are effected using a winding stem in the form of a movable â€œwinchâ€ that links directly to one of the small â€œcapstansâ€ that are found at the four exterior angles of the case: at the upper left, it acts directly on the fusee and, by the intermediary of the chain, allows the barrel to be wound; at the upper right, it acts on the minute cylinder which is connected to that of the hours. The two other small â€œcapstansâ€ are only there for decoration and to complete the aesthetics of the case. Once the small winch is used, it is easily stored in the buckle of the watchâ€™s bracelet.
Complication for complication’s sake? You decide.
