Steel perpetual calendars from manufacture movements are rare at any price. The L.U.C Perpetual Calendar gives you moonphase, day, date, and month driven by Chopard's own 96.10-L caliber, in a 43mm case that costs a fraction of what Geneva's most famous perpetuals command. It is an honest collector's watch: no prestige markup, just serious horology.
Chopard launched the L.U.C line in 1996 as a deliberate push into manufacture watchmaking, separating the L.U.C atelier from the brand's fashion and jewelry output. The 96.10-L perpetual calendar movement followed as one of the more ambitious calibers in the line, displaying the four classic perpetual functions with a moonphase accurate to one day in roughly 122 years. The 161942-5001 in steel has been in production since 2014, and it remains a relatively quiet reference: Chopard's marketing tends to favor gold variants, which keeps steel examples off many buyers' radar.
That low visibility is precisely what makes it interesting to collectors who know the movement.
The 43mm diameter is genuine, not padded by thick lugs, but the case is tall due to the movement's construction and the calendar module above it. Wrist presence is substantial and the watch may wear large on smaller wrists. Chopard's secondary market for L.U.C perpetual calendars is thin, particularly in steel, which cuts both ways: prices are attractive on entry, but finding a buyer if you need to sell quickly requires patience.
Service intervals matter here because a perpetual calendar movement accumulates complexity fast; insist on a full service history, not just a seller's word that it "keeps perfect time." Parts and service must go through Chopard's network, and while availability is currently good, L.U.C is a specialty segment within a mid-sized brand.
Pre-owned examples of the 161942-5001 in steel typically trade well below retail, which sits in the mid-five-figure range new. A clean example with box and papers can be found in the $15,000 to $22,000 range depending on condition and service history, representing exceptional value relative to competing in-house perpetual calendars from more prominent names. Steel variants carry a modest premium over gold on the secondary market, which is the inverse of the retail relationship and reflects genuine collector demand rather than speculative buying.
The 96.10-L is Chopard's manufacture perpetual calendar caliber and requires service at a Chopard authorized center or an independent specialist with documented L.U.C experience. Recommended service interval is approximately five to seven years; resetting the perpetual calendar functions after a service requires careful procedure, so confirm your watchmaker is familiar with this specific caliber before committing.
