CORUM Ti-Bridge Power Reserve Red Gold Limited Edition, Ref 107.101.05/0F81 0000

Introduced in 2011, the CORUM Ti-Bridge collection now welcomes a new member to the family of watches based on linear time concept.

The CORUM Ti-Bridge Power Reserve in titanium was the reference model of this collection when it launched last year. In 2012, the brand is expanding this line with a new Ti-Bridge Power Reserve model in Red Gold case that offers a contemporary interpretation of the Golden Bridge spirit.

The movement remains same: Caliber CO107. The sobriety of the red gold adorning the case makes a perfect match for the titanium of this hand-wound baguette movement. The horizontal baguette movement held by four ruthenium-coated bars excels in its role of epitomizing unique and absolute horological purity.

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.
