When the brand Corum created the Golden Bridge in 1980, did its founder René Bannwart suspect that he had just launched a model which was not only going to become one of the pillars of his company but also an icon of the Swiss watchmaking?
The remarkable design of this timepiece all in transparency was certainly in line with the philosophy of a brand which wished from its creation to take place in the avant-garde of the watchmaking industry. The model completed an already very creative collection alongside with the very sporty Admiral’s Cup watch. It also reached a branch of the watchmaking industry where no other watchmaking manufacturers had chosen to venture: the one of the “baguette en ligne” movement.
Thirty years later, this movement, which meanwhile became mythical, remains an exceptional achievement and a unique watchmaking expression. Composed of 140 components arranged in a parallelepiped rectangle of 33 mm in length, 3 mm in width and less than 5 mm in thickness, it is a masterpiece of micromechanics offering a balance wheel with variable inertia, a barrel with slipping spring, a power reserve of 40 hours, a 4 hertz frequency ensuring reliability and precision, and hand-engraved bridges and plate made of fine gold… At this level of miniaturization, there are few other pretenders.
The Miss Golden Bridge proposes a feminine expression of a design which has made his mark on the watchmaking history. It’s in a whole new ceramic case that the coveted movement is staged. The technical challenge that confronts this material is high because the fineness of the ceramic case is against a large proportion of sapphire crystal. The slim black case just supervises the movement of gold, marking a break between colors and shapes. The faceted hands overlap with lightness the CO113 caliber. The middle, opened above, below but also on its sides, still plays many effects of transparency and allows the movement to be admired from all parts, through its sapphire glasses. However, it comes rethought in a very feminine spirit, in a thin, slender and curved tonneau shape. Its horns were removed so that the hand-stitched crocodile bracelet perfectly integrates the case, setting itself in its continuity, in the style of a cuff watch. The crown located at 6 o’clock emphasizes the refined character of this contemporary and elegant case.
At the time of the thirty-fifth anniversary of the famous Golden Bridge model, all credit is also to men, as a new model is entirely dedicated to them. Always true to its avant-garde reputation, Corum chose the compromise between a traditional dial and a simple sapphire crystal. The new Golden Bridge model introduced in 2015 is indeed equipped with a metallic glass background. This treatment applied directly on the sapphire crystal allows a clever play of transparency – sometimes opaque on the wrist, sometimes translucent to light. The lines enshrined by the metallization movement make echo to the gold baguette. Devoid of any index, only faceted hands break this verticality. Following the example of all the details which make of this timepiece a masterpiece, the calibre CO113 is also visible from the back of the watch, through the sapphire crystal caseback.
