Among other novelties, Corum has scheduled the unveiling of its new Titanium Bridge Automatic Dual Winder for the upcoming Baselworld 2013 fair. The new timekeeper will display a new proprietary CO 27 caliber which features a unique winding system with two interconnected inline oscillating weights that has an uncanny resemblance to the wheels of a steam locomotive. Besides, the movement sports the distinctive linear design which is characteristic for the Bridges collection and overall futuristic and modern appearance.
The newcomer is the first model with the automatic winding from the Titanium Bridge (also known as Ti-Bridge) lineage which was introduced three years ago and which is a part of the larger Bridges collection (the Bridges series first appeared in the 1980s). It is quite commendable that the brand opted to use an innovative mechanism for the first self-winding piece in the Ti Bridge line of products. As it has been mentioned, the watch has a new patented inline winding system. The mechanism incorporates a pair of oscillating weights coupled by a transmission arbor which causes that the both weights move synchronous, regardless of the direction of the turning. Its ability to wind the movement is enabled through the inclusion of three stacked mechanisms consisting of a single ball bearing device and a pair of bidirectional ball bearing clutches which are manufactured in ceramics and thus they do not require any lubrication. On the top of each of two oscillating weighs, there are two disks made of steel, while the smoothness of winding is insured with a pair of 1.32 g tungsten semi-cylinders.
Corum Ti Bridges Automatic Dual Winder stays consistent with the aesthetics of the series which features movements with horizontal linear architecture placed inside a tonneau shaped case with the length higher than width. As it is the case with all of the timepieces from the series, its movement is held by four titanium crossbars that make the caliber appear suspended in mid air. The in-house caliber which was designed and produced by Corum is visible through the skeletonized dial with luminous skeleton hands. Its patented winding system with inline oscillating weights is featured at the back of the case. CO 27 Caliber is supplied with a single barrel that sits at the three o’clock position and enables the power reserve that lasts for about three days.
The new model which will be unveiled at the Baselworld 2013 event is placed into a fairly large casing with the width of 42mm and the length of 52mm. It has a curved profile and the smaller thickness than its predecessors, though it is still unknown what it is precisely. There are two versions of the timekeeper and both of them will be launched in a limited edition. The basic version in grade 5 titanium will be made in 200 copies, whereas the more exclusive 5N 18 K red gold variation includes only 25 pieces.
