“The only simple things about the Cu29 are its functions. For the rest, there was no compromise.”

Hervé Schlüchter

Inspired by history.

Copper has been known across cultures for millennia for its benefits to the body and its potential to soothe certain ailments. Inspired by these beliefs, the Alchemists imagined how a timepiece could capture their essence, which led them to develop the Cuprum 479, a new innovative horological alloy, but also to reflect on its field of expression in their works. In this case, by placing it in contact with the skin thanks to the bottom of the case, made entirely with the alloy, delivering their interpretation of this historical lore.

Cu29, Mechanical Healing.

The case of the Cu29 is crafted exclusively in Cuprum 479. The crown is also made of Cuprum, as well as the pin buckle, bottom plate, dial’s base, hours, minutes and seconds hands as well as the majority of the bridges. The Cu29 is a true horological masterpiece from Hervé Schlüchter, following traditional horological art methods and teachings transmitted from Philippe Dufour, a Master of the craft, which the Alchemists’ watchmakers strive to master perfectly. Convinced that the emotion they invest in the creation of the timepiece will be transmitted to its wearer.

The Cu29 is an invitation to a journey transcending time: the quest for the essential.

The Cu29 represents a demonstration of centuries-old watchmaking skills and an ode to traditional horological arts. This inaugural piece is the precursor of the Alchemists’ future and of their humble will to preserve a horological heritage.

Movement with inverted architecture.

The atypical arrangement of the Cu29’s functions has led to the total transposition of the movement’s architecture. The manufacture calibre is completely inverted compared to the traditional design in which the hours, minutes and seconds are in the centre and the double barrels linked in parallel extend directly from the winding stem.

As in traditional horological timepieces, the Cu29 is constructed around notions such as volume and symmetry. This 3D architecture is highlighted by the first “atmosphere crystal” of watchmaking.

In the Cu29, the symmetry of the double barrel at 6 o’clock offers a totally unique visual spectacle during the winding process, which allows you to see each spring of the suspended moustache-shaped pawl wind with each click of the ratchet until the timepiece is fully wound.

The Cu29's hybrid case is composed of a unique sapphire crystal, opening new horizons.

Shape
It is hemispherical. The base of this atmosphere crystal has a smaller diameter than that of its outside edge, meaning that the crystal’s diameter gradually expands from the base until it takes on a hemispherical curve at its apex—exactly like the earth’s atmosphere, from whence it gets its name.
Construction
The Cu29’s atmosphere crystal is pierced by the crown tube, which is usually found in the case middle. Here, it is integrated directly into the atmosphere crystal.
Casing
This atmosphere crystal has forced the Alchemists to perform the casing from below. The movement is thus screwed to the case middle, which is then covered by the atmosphere glass. Finally, the Cu29 has no bezel or flange, thus enabling the movement to occupy the entire case.

Cu29: personalization and precious gemstones

The Cu29 is a creation that can be highly personalized by the integration of dials, offered in different stones, up to the customers’ preferences. The selection of these gemstones was guided by their elegance, but also by the primary inspiration around the concept of the timepiece.

The notion of “lithotherapy” is recurrent in the usages of certain cultures since time immemorial. It appears that certain people may be sensible to certain kinds of stones and crystals, by being in contact or in close proximity with them. While no scientific proof backs up this theory, these gemstones would have beneficial effects on these persons’ well-being and could promote certain states of mind.

The Alchemists, intrigued by this philosophy wanted to give their interpretation and thus went on a quest to find sublime gemstones to ornate the dials of the Cu29. All while being guided by the eventuality that these stones might also favor certain vertues for their wearers.

Haute Horlogerie hand finish.

The entire calibre and case are hand finished, with traditionally buffed and polished corners, drilled and hand-polished balance bridge and sweep second cock, escapement wheel on black-polished endstones, rounded and moveable Geneva hairspring stud holder, moulded, ringed and bevelled wheel and intermediate wheels, and black-polished and hand-blued screws.

The hours, minutes and seconds hands are rounded by hand and then blued and lacquered. The power reserve and selector dial is made of black-polished steel adorned with a lacquered engraving. The double barrels linked in parallel are bevelled and polished by hand. Each calibre leaving the Alchemists’ workshop is then individually numbered.

All the Cu29’s parts thus obtain genuine added value from the watchmaker’s hand. The Alchemists have no finishing workshop: the watchmaker receives the kit for each watch as a “blank”, meaning non-finished, and must do the hand-finishing him- or herself, as done back in the glory days of fine watchmaking and which very few traditional Maisons still know how to do today.
