Corum 10th Anniversary Golden Bridge Automatic Collection

Swiss luxury watch brand Corum is celebrating the 10th anniversary of its Automatic Golden Bridge watch with the launch of new Automatic Golden Bridge series.

The most emblematic high-horlogerie creation from Corum, the Golden Bridge was released in 1980. It premiered the world’s first-ever in-line baguette movement. Just over 30 years later, in 2011, Corum released an automatic version of the in-line movement.

Now, in celebration of the 10th anniversary of the Automatic Golden Bridge, Corum takes another leap, unveiling a new Automatic Golden Bridge series with avant-garde case that delivers sweeping views of the meticulously finished movement.

The original in-line movement was first created in the 1970’s by Italian watchmaker Vincent Calabrese. He presented his patented concept, a 45-piece highly skeletonised in-line movement, at the 1977 Geneva International Inventors’ Show and Corum immediately acquired the patent and worked with Calabrese to develop the revolutionary movement.

The first Corum Golden Bridge, with movement parts made of gold, made its debut at the 1980 Basel Fair. The Corum Golden Bridge Automatic, unveiled in 2011, ushered in a new era for this contemporary icon.

In honor of the 10th anniversary of the automatic in-line movement, Corum releases the new Golden Bridge Automatic series. Consisting of four models, the tonneau-shaped case offers a dramatic view of the movement thanks to the panoramic sapphire crystal and case back in a larger size.

Also, for the first time, Corum creates the sapphire crystal as a single sapphire piece that extends from the top crystal to the sides of the watch – allowing for a 360-degree view inside.

The new versions feature cases in polished Grade 5 titanium with the crown at 6:00 for ergonomic comfort and for aesthetic appeal.

They include a titanium and 18-karat gold model in a limited edition of 150 pieces, and a full titanium version in an edition of just 50 pieces. These timepieces are also available with diamond-set cases. Just 100 pieces of the diamond-set titanium-and-gold version will be produced, and only 25 of the diamond-set titanium watch will be made.

Additionally, Corum has invented a discretely placed floating harness system for its hand-applied indexes, yielding a highly modern and sophisticated flair. The design is actually born out of the need for function.

Because there is no dial to affix the indexes to, the harness system links to the movement base so that the markers seem to be floating in space. As indicated in the series name – Golden Bridge – the main plates and bridges of the movement are in 18-karat gold for all versions.

All these watches boast a sapphire case back made of smoked crystal for an almost mystical look. Additionally, they are all powered by the original automatic movement that remains incredibly advanced even by today’s standards.

With all of its 194 parts in one line, the exclusive Corum Caliber C0313 boasts 40 hours of power reserve, a variable inertia balance wheel for long-term precision, a miniaturized barrel and main plate, bridges made of 18- karat gold, and a platinum linear oscillating weight.

Water resistant to 30 meters, the Corum Golden Bridge Automatic 10th anniversary watches are finished with a soft-touch alligator strap and triple folding clasp.
