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. Sapphire is one of the most difficult materials to deal with as it is brittle and can break in the manufacturing process. It also requires special attention to corners and metal case connections to render the watch water resistant. However, Corum’s in-house engineers and watchmakers have mastered the process with this single piece that covers the top and sides.
The new versions feature cases created in polishable 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. Each of these two materials are also offered with diamonds set on the case. 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.
