Vacheron Constantin's Harmony Collection Adds a Complete Calendar

Vacheron Constantin's Harmony Collection Adds a Complete Calendar

November 21, 2016

On the occasion of its 260th anniversary, the Manufacture Vacheron Constantin unveiled the Harmony collection, which was immediately regarded as a stellar collection. Designed as authentic watch sculptures featuring sophisticated technical content, the timepieces composing the range were housed in an unusual cushion-shaped case featuring pure, graphic lines.

Made in-house: caliber 2460 QC

After the limited series supporting the launch of the collection, Vacheron Constantin is now introducing new references equipped with several in-house calibers and developed around the chronograph, tourbillon or dual-time complications.

One of the standouts is a remarkable Harmony complete calendar model. Equipped with an unprecedented in-house movement, it joins the ranks of these precious mechanical timepieces, all certified by the prestigious Hallmark of Geneva.

The maison Vacheron Constantin is the world's oldest watch manufacturer engaged in uninterrupted activity since its creation in 1755. One of the brandís first wrist chronographs, dating from 1928, inspired the cushion shape and the eminently contemporary design of the models composing the Harmony collection. Its generous cases with reinvented lines are particularly suited to housing medium and high complications and grand complication calibers.

The age of the moon is indicated on the dial.

In 2016, the Harmony collection welcomes a useful, technical and sophisticated horological complication: the complete calendar. The classic and elegant design of the cushion-shaped rose gold case strikes a perfect balance with the optimal readability of the dial indications. Around its rim, the date is indicated by a central hand that culminates in a burgundy crescent.

The day and month, in the same deep red, appear through apertures in the upper half of the dial, while the lower half is devoted to displays of the moon phases and the age of the moon. These remarkably precise astronomical indications require adjustment only once every 122 years, instead of every three years for a conventional moon phase.

An all-new self-winding movement, Caliber 2460 QC entirely developed and manufactured by Vacheron Constantin powers this complete calendar. Equipped with 308 components, it beats at a frequency of 4 Hz. A transparent sapphire crystal caseback provides an admirable view of its inner workings and its high-end finishing.
