There’s traditional watchmaking, and then there’s ultra-complex timepieces that make you stop and actually study how it all works. That’s exactly how the horological world views Vacheron Constantin’s Les Cabinotiers Minute Repeater Tourbillon Skeleton, recently unveiled as part of Watches and Wonders.
It’s a one-off, built around the Caliber 2755 TMR SQ, pairing two of watchmaking’s most respected complications, a tourbillon and a minute repeater, and then skeletonizing everything so you can see it all in motion. The watchmakers spent a full year reworking the movement into its openworked form, housed by a 45mm 18k gold case and a sapphire dial that keeps the view completely unobstructed.
What really shines is how thoughtfully everything has been executed. The minute repeater uses a silent centripetal regulator instead of a usual anchor system, which means the chimes flow more evenly without the background buzz you’d normally hear. The tourbillon, beating at 2.5 Hz, offers unmatched precision and art in motion that collectors are willing to pay a premium for. About 40% of the material has been removed from the mainplate, but it still maintains its ruggedness and practicality.
There are nine different techniques used across the 473-piece design, which is a lot considering the movement is only 6.1mm thick. Some parts are treated in darker anthracite tones, others left in brass or steel, creating subtle yet eye-catching contrast. You’ll even spot subtle references to the Maltese cross worked into the design if you look closely. It all adds up to a one-of-a-kind Vacheron Constantin that’s both a collector’s showcase piece and a look into what modern haute horlogerie can look like when a brand has no limits.
