Harry Winston Opus III made by Vianney Halter

With its completely mechanical digital display, the Opus III (presented at BaselWorld 2003), is innovative in several domains. First of all, the movement of the Opus III has been completely redesigned. Even though the double barrel, escapement and balance wheel remain traditional, the physical disposition has been totally reorganized, from the bottom plate to the gear trains. Secondly, the time reading mechanism is totally original. It is composed of ten superimposed discs that display the hours, minutes and seconds in different windows. Thirdly, the crown and case are innovative. The single horizontal crown moves from top to bottom in four adjustment positions. The first position is for winding; the second adjusts the minutes; the third adjusts the hours, while the fourth position controls the date.
