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.
