Corum has released a new watch in its “Bridges” collection — which includes the classic Golden Bridge and modern Ti-Bridge models — outfitted with an innovative automatic winding system in a horizontally oriented, linear movement.
The Corum Ti-Bridge Automatic Dual Winder, which made its debut at this year’s Baselworld watch fair, features an in-house movement with two in-line-mounted circular oscillating weights, connected by a transmission arbor that makes them move in parallel whatever the direction of rotation. Three integrated, stacked mechanisms at 9 o’clock – a ball bearing device and two unidirectional ball bearings clutches (made of ceramics and thus requiring no lubrication), ensure that the winding is efficient in both directions of the oscillating weights’ rotations. There are two steel disks atop each of the oscillating weights, and two 1.32-gram tungsten semi-cylinders for smooth winding. A single barrel, located at 3 o’clock, stores the movement’s 72- hour power reserve.
The Ti-Bridge’s movement, Caliber CO 207, is mounted in the center of the horizontal rectangular case, suspended by four titanium crossbars. The dial, in anthracite gray, frames a large transparent window through which one can view the linear movement. The tonneau-shaped case measures 42 x 52 mm, and is slimmer than those of its predecessors in the Ti-Bridge collection. The caseback has a rectangular aperture that offers a rear view of the movement and its two unconventional oscillating weights. The case is water-resistant to 30 meters and is available in either polished grade 5 titanium or 5N 18k rose gold. The Corum Ti-Bridge Automatic Dual Winder is fitted with either a rubber-type leather strap or a grade 5 titanium bracelet. Prices range from $22,300 to $51,000.
