It is rare to see a minute repeater, a split-seconds chronograph and a tourbillon regulator together in a wristwatch but Vacheron Constantin’s newest Les Cabinotiers Temporis Duo Grand Complication Openface has overcome the challenge with its latest technical developments and continuous research into materials.
This, is in addition to the decoration and hand-finishing of Calibre 2757 S, which comprises almost 700 components including a complex sapphire dial and the sapphire back of the 45mm 5N pink gold case.
As the aesthetic signature of the new Les Cabinotiers Temporis Duo Grand Complication Openface, the 0.5mm thick transparent sapphire dial is distinguished by a highly complex mix of finishes featuring polished and frosted surfaces on the counters, hour markers treated with grey NAC and chronograph markers that are engraved and inked.
The 30-minute chronograph counter hand and the two chronograph seconds hands are made of PVD-coated aluminium in olive green, which matches the green alligator leather strap which attaches the 45mm pink gold case to the wrist.
On the reverse side of the movement, you’ll find a distinctive decoration where the surface of the blackened bridges have been hollowed out then sandblasted by hand to a very fine grain and edged with a mirror-polished sink.
As a result, the beauty of the movement architecture has been amplified by the contrast between the black bridges, its polished borders and the golden tones of the moving parts. There’s even a homage to Jean-Marc Vacheron with the initials JMV engraved and held by a semi-circular bridge that has been round-polished by hand.
