L.U.C 03.03-L

Any Haute Horlogerie manufacture needs to have an excellent chronograph movement in its technical portfolio. Mission accomplished for Chopard Manufacture since 2006, the date of its 10th anniversary. The exceptional chronograph movement, L.U.C Calibre 03.03-L, is fully integrated and features a column-wheel system and a vertical coupling clutch equipped with a friction organ in a viscoelastic material. Three other patented devices further enhance its reliability and its user friendliness. The first is a zero-reset mechanism via three supple hammers ensuring an optimal return of the three hands and absorption of the resulting shock. Secondly, the watch can be set to time with great accuracy because L.U.C Calibre 03.03-L (L.U.C 11CF) has a small seconds reset system coupled with a stop seconds device. And finally the automatic winding system is self-locking in order ensure optimal winding in either direction of the oscillating weight thanks to its gear system. Its excellent performances along with the precision ensured by its Variner balance wheel enable L.U.C Calibre 03.03-L to earn chronometer certification from the Swiss Official Chronometer Testing Institute (COSC).
