The balance wheel oscillates precisely over the arbor of the second wheel in the centre of the rotating frame. This frame revolves around the second wheel, which is firmly screwed down. Consequently, when the second wheel completes a revolution once every minute, the tourbillon turns too. This means that errors caused by the timepiece’s position or centre of gravity no longer occur repeatedly but instead are compensated for once a minute.
The Opera Tourbillon table clock is therefore not simply a functional lifestyle accessory – it also comes with a highly sophisticated horological complication. The skeletonised dial is protected solely by glass, allowing a glimpse of the timepiece’s inner workings. Working on the basis of a gold-plated gear train developed in the manufacture, the clock-makers have succeeded in realising their vision of a reliable, low-maintenance and durable table clock. The clock is fitted with a mechanical constant-force mechanism comprising a fusee and steel cable, to counter the fact that the driving force stored in the mainspring gradually decreases over the course of the 15-day power reserve period. The movement is highlighted by the one-minute flying tourbillon, which has been crafted by hand in the manufacture.
The entire glass construction rests on a wooden base coated in black varnish and decorated with real metal inlays. This timekeeping gem is supported by just four chromed brass bars, creating the impression that it is floating.
This is a complicated process that makes the Opera Tourbillon a particularly valuable timepiece from a technical perspective too, and one that meets the standards of traditional clock-making in all respects.
