Corum Golden Bridge Tourbillon Limited Edition

In 2010, Corum celebrates the thirtieth anniversary of its extraordinary Golden Bridge. During its thirty year history, its immediately recognizable esthetical codes and fascinating baguette movement have made the Golden Bridge an emblem of CORUM, and an icon of high horology.

To celebrate this anniversary in style, the watchmakers of the brand have worked together for two years to create the caliber CO213, a masterwork in terms of micromechanics, housing 182 components on a tiny baguette measuring 33mm by 3mm. Combining traditional watchmaking and high-end materials they write a new chapter in an already rich watchmaking history.

Indeed, CORUM has created the first baguette movement with a tourbillon escapement, housed in the world’s smallest cage – 8.5 mm in diameter – with an escapement in Silicium.

Beating at 19’200 vibrations per hour, with a power reserve of 40 hours despite a miniaturized barrel, which is almost hidden by the movement, the new caliber CO213 has also been designed in line with the codes of high horology.

Its plate and bridges are crafted in 18kt gold and hand-engraved with patterns replicating the shape of tree ferns from the Jura region, the cradle of watchmaking and home to CORUM. No detail has been left to chance; even the upper bridge of the tourbillon cage reproduces the characteristic shape of the brand’s emblem, the key crafted in titanium.

This movement is housed in the legendary Golden Bridge case. The dials are set behind the mechanism and are worked in various materials such as meteorite, enamel, semi-precious stones or mother-of-pearl with different finishes. On the bottom of the case the opening also takes the shape of a lock, echoing the brand’s mantra: “Unlock and Conquer”! This watch is water-resistant to 30 meters.

The Corum Golden Bridge Tourbillon watch will be produced in 33 unique pieces only: 16 in red gold, 11 in white gold and 6 in Platinum.
