Key Features

This watch is based on the original Vacheron & Constantin movement from a pocket watch, and according to the catalogue, its serial number corresponds to 1910.

The gold case was melted down for scrap long ago, but thankfully the watchmakers kept the expensive, high-quality movement. The new steel case was made specifically for this movement, and its classical, attractive shape makes the watch a worthy and modern accessory. The antique movement can be admired through the glass caseback. There is a button for setting the hands next to the crown.

The convex shape of the enamel dial, combined with the vintage signatures in a style that dates back to the French Revolution, creates a special volume under the glass, while the dark blue ‘fleur-de-lis’ hands complement the image. Connoisseurs of numerology can also admire the beautifully shaped threes and zeros.

The integrity of the mechanics is excellent, and everything works reliably.
