Corum - The new Ti-Bridge Power Reserve

Corum The new Ti-Bridge Power Reserve

#wtbasel / The linear time concept.

Press release

Presented in 2011, the Ti-Bridge Power Reserve in titanium has established itself as a reference model, a signature watch blending aesthetic appeal and top-flight mechanics. Allying the precious nature of red gold with titanium, Corum has devised a new version of this exceptional model offering a contemporary interpretation of the Golden Bridge spirit. The horizontal baguette movement held by four ruthenium-coated bars excels in its role of epitomizing unique and absolute horological purity.




Corum is enriching its Ti-Bridge collection with a model that plays with materials in order to sublimate them. The sobriety of the red gold adorning the case makes a perfect match for the titanium of the hand-wound baguette movement, Caliber CO107. The association of these two materials is so powerful and so modern that it ideally combines with the architectural codes of the watch. Above and beyond their precious nature, the linearity and depth of the parts is further enhanced in this model. Red gold ennobles the watch from case to crown and creates a striking contrast with the titanium of the movement. The applied gilded logo and hour-markers embellish the dial, while the hour and minute hands as well as the power-reserve indicator are coated with luminescent material in order to be readable even in the dark. Fitted with a crocodile leather strap secured by a gold triple folding clasp with two safety pushers, the Ti-Bridge Power Reserve is issued in a 50-piece limited numbered edition.

At its heart beats a worthy representative of horological nobility, Caliber CO107, which drives the hour and minute functions as well as the power-reserve indication. Reflecting the structured geometry of this timepiece, the linear power-reserve was a natural choice. To achieve this, Caliber CO107 is fitted with a satellite going train that is visible when viewing the watch sideways along the 9 – 3 o'clock axis, but invisible when looking face on at this Ti-Bridge watch. This module features several specific characteristics, including a differential system composed of three wheels, including an offset planetary wheel. Depending on its rotation direction, the latter spins either on its axis or around that of the two other wheels, thereby linking the barrel on the one hand and the winding stem on the either to the power-reserve indicator – and all within a minimum of space.




Another specific feature developed for this caliber is the power-reserve indicator fitted on a toothed sliding piece in phosphate nickel. The choice of this material, combined with a “LIGA” manufacturing process – an acronym derived the German words for lithography, electroplating and molding -– which is a type of electroforming, serves to create a part with far more precise measurements than those achieved by classic mechanical machining. It thereby guarantees the extremely accurate indication of the level of the power reserve – which in this case amounts to three days in all.




Firmly in the forefront of a profession that it exercises at the peak of excellence, Corum continues to create ever more audacious watches – an approach perfectly exemplified in the red gold Ti-Bridge Power Reserve. Design matches high technology as they jointly open up vast new horizons.
