Corum pays tribute to its Golden Bridge with two new limited edition models, each celebrating the watch’s 40th anniversary. Corum has frequently revisited the Golden Bridge in the forty years since the watchmaker debuted its first watch with the linear-gear movement.
The architecturally sublime caliber, initially designed by Vincent Calabrese, was re-engineered by Corum in 2011 and has been variously offered since then with manual winding or automatic winding. While Corum usually places the in-line movement in a rectangular or tonneau case, Corum began offering the movement within round cases for the first time in 2016 with precious metal and gem-settings.
With these two anniversary Golden Bridge models, Corum returns to the original manual-wind caliber designs. In the Caliber CO113, the viewer’s eyes are drawn along the path following the movement’s energy transfer, starting at the spring barrel at 6 o’clock up to the escapement at 12 o’clock.
White gold or rose gold
With this commemorative offering, Corum emphasizes the Golden Bridge’s original rectangular case. Two 29.5mm by 42.2mm models, one in white gold and one with a rose gold case, celebrate not only the Golden Bridge’s anniversary, but also an aspect of Corum’s own history as a new watchmaking company, founded in 1955.
On the white gold Golden Bridge Rectangle 40th anniversary model, Corum hand-engraves flowers onto the case in reference to its ongoing collection of Haute Horlogerie models. The depictions of the acanthus and fern plants are a nod to a style created in Corum’s home of La Chaux-de-Fonds. These are the same engravings Corum has placed on all Golden Bridge baguette movements since the timepiece was launched in 1980.
The white gold Corum Golden Bridge Rectangle 40th Anniversary is limited to three pieces honoring Corum’s three co-founders.
With the rose gold edition of the Golden Bridge Rectangle 40th Anniversary watch, Corum is also celebrating its own sixty-fifth birthday. This 18-karat rose gold version will be made as a limited edition of forty pieces, each engraved “Limited Edition 1 0f 40” inside the case at 3 o’clock. In addition, you’ll find the Corum key logo metallized in an eye-catching, light-diffusing pattern on a sapphire crystal caseback. 
Prices: $39,800 (rose gold, limited edition of forty pieces), $42,800 (white gold, limited edition of three pieces).
