The new Métiers d’Art collection from Vacheron Constantin combines traditional horological techniques and artistic crafts like engraving, pounced ornament decoration and plique-à-jour enamelling.
The Métiers d’Art Les Aérostiers collection pays tribute to five historical flights made in France in the late 18th century by balloonists known as aérostiers in French language. On the scale of a watch dial, the master engravers of the Maison faithfully reproduced in miniature the historical depictions of five flights undertaken in France between 1783 and 1785. Equipped with a self-winding manufacture calibre that powers a disc based display instead of hands, these timepieces proudly display splendid hand engraved and micro-sculpted gold hot-air balloons hover against a translucent plique-à-jour enamel background.
In order to create the challenging artistic background for this timepiece, the master engravers of Vacheron Constantin have added volume to the original two-dimensional drawings, and interpreted their colours through finishing effects. Each hot-air balloon called for up to three weeks of craftsmanship in order to reproduce the entire range of subtle feature and ornamental details of the original works. The dials thus compose authentic miniature scenes graced with an extraordinary variety of motifs.
The pounced ornament technique consists in removing material so as to fashion relief effects. This irreversible operation calls for an impeccably deft touch. The master engraver first traces the volumes using a drypoint technique, before sculpting the precious mass and creates a particularly delicate rounded effect. This stage serves to carve out the curves of the balloon and the basket, as well as the lines of the ropes. The burins are repeatedly sharpened so as to achieve extreme precision. The level of finishing becomes ever more sophisticated, all the way through to the smallest details of the human figures, animals and the meticulous decoration of the balloons. The light effects playing over the different gold textures naturally influence the visual appearance of the surface.
On the dials of the Métiers d’Art Les Aérostiers collection, a translucent background in sky blue, dark blue, turquoise, brown or burgundy, evoke a spirit of airy transparency. Vacheron Constantin is for the first time calling upon this skill mastered by very few enamellers. Its layout is reminiscent of cloisonné enamelling; while the absence of a base recalls a miniature stained-glass window. The balance between the various shades is extremely subtle, as is the polishing of the partitions between them.
The predominant shades of each creation are also picked up on the display discs as well as the matching strap. The inner bezel ring framing the enamel is engraved with a motif inspired by balloon ropes, also varying between 3N, 4N or 5N gold according to the models.
Transparency effects provide fascinating glimpses of the gear trains and discs of Calibre 2460 G4/1 through the plique-à-jour enamel. The disc-type display is cleverly revealed through apertures around the rim of the dial, between the curves of the plique-à-jour enamel partitions.
The hours, minutes, day of the week and date are shown by means of four discs: respectively two of the dragging type and two of the jumping variety.
The calibre decorated according to the highest watchmaking finishing standards is generously visible through the transparent caseback. The gold oscillating weight, specially engraved and domed for this new collection, evokes the rounded shape of a hot-air balloon.
Brilliantly interpreted by the master artisans of Vacheron Constantin, the five flights each come in an exclusive limited numbered edition of five.
