Cornavin OH.05.B
The Cornavin OH.05.B is a Swiss Made watch with a Open Heart automatic movement. The front and back are protected by sapphire crystal and allow a fascinating view into the watch from both sides. The blue, semi-transparent dial is decorated with a subtle honeycomb-pattern. The aperture at 12 o'clock shows the balance wheel of the automatic movement.
The 42mm case of the Downtown Open Heart Automatic Collection is made from high-quality rosegold PVD-coated 316L stainless steel. A mixture of polished and satin-brushed finishes underline the aesthetics of this case design. The crown carries the debossed ‘C’ emblem.
The elegance of a seamless continuity from case to bracelet is ensured by our unique attachment design. This watch is paired with a durable, rosegold PVD-coated 316L stainless steel bracelet.

SWISS MADE AUTOMATIC
Since 1922 Cornavin strives to create unconventional Swiss timepieces. Our designs are unexpected and exciting, yet remain traditional in their handcrafted Swiss origin. The Downtown Open Heart Automatic Collection pushes the limits of combining transparency with design, without compromising functionality and accuracy.
DOWNTOWN OPEN HEART AUTOMATIC COLLECTION
The Downtown Open Heart collection highlights the heart of its automatic movement. The aperture at 12 o'clock reveals the balance wheel and the passing of time. The strong Cornavin DNA is not only found the Downtown case design, but also in the semi-transparent honeycomb dial.
