CORUM Ti-Bridge Automatic Dual Winder

A world first for the new Ti-Bridge

The latest addition to the Bridges collection by Corum, the Ti-Bridge Automatic Dual Winder, heralds a new chapter in watchmaking history. Perfectly in tune with the collection’s linear architecture, the new Dual Winder system of the automatic CO 207 caliber – designed, developed and patented by Corum – derives its energy from two interconnected inline oscillating weights. A world first for this avant-garde timepiece.

A patented revolutionary winding system, a new Manufacture movement, a new titanium case and a structure reflecting the collection’s signature linear construction: the Ti-Bridge Automatic Dual Winder by Corum is a truly exceptional timepiece.

In designing and developing the first automatic watch within the Ti-Bridge line, the Corum master-watchmakers have remained entirely loyal to the fundamental principles that have guided the history of this collection: namely the horizontal linearity of both the case and the movement. To enrich the Ti-Bridge line with its first automatic caliber, the Corum movement constructors chose to develop an inline winding system. The patented Corum Dual Winder system features two inline- mounted circular oscillating weights, interconnected via a transmission arbor that makes them move in parallel, as if performing a perfectly choreographed ballet, whatever the rotation direction. Thanks to three integrated stacked mechanisms at 9 o’clock – a ball bearing device and two unidirectional ball bearings clutches – made in ceramics and thus requiring no lubrication – the winding is efficient in both directions of the oscillating weights’ rotations. Two steel disks top each of the oscillating weights, while two 1.32-gram tungsten semi-cylinders ensure smooth winding. A single barrel placed at 3 o’clock stores up the CO 207 caliber’s 72-hour power reserve.

True to the aesthetic of the Ti-Bridge line, the new CO 207 movement is held in the center of the case by four titanium cross-bars. The impression of a suspended mechanism is further accentuated by the line’s intrinsic transparency, framed by an anthracite grey dial.

Featuring the collection’s typical tonneau shape, the generous 42 x 52 mm case is slimmer than its predecessors and has a broad front opening revealing Caliber CO 207, as well as a rectangular rear aperture onto the rotating mechanism and its two unusual inline oscillating weights. Water-resistant to 30 meters and fitted with a domed sapphire crystal, the Ti-Bridge Automatic Dual Winder is available in grade 5 titanium – the only titanium alloy that can be polished – fitted with a rubber-type leather strap or a grade 5 titanium bracelet. The Ti-Bridge Automatic Dual Winder also comes in a 5N 18kt red gold.

With the launch of the first automatic watch in the Ti-Bridge line, powered by a patented movement with two interconnected inline oscillating weights – a world first – Corum reaffirms its capacity for constant technical innovation in nurturing the distinctive collections endowed with a powerful aesthetic that has become the unmistakable brand signature over the past decades.
