The decorative craftsmanship displayed in the Tecnica Palme equals the technical mastery of the watchmaking itself. Given that its movement features a tourbillon, a minute repeater, a perpetual calendar and a chronograph, it's difficult to imagine how any decoration could compete. And yet... The eye cannot help but be captivated by the shimmering brilliance of the palm leaf motif that adorns this piece; it owes its beauty to the art of engraving and Grand Feu enamelling.

The Tecnica Palme's decorative odyssey begins in the Parmigiani Fleurier manufactures of the watchmaking centre, which supply two plates (one for the dial, one for the double case-back) in a special "enamellable" alloy of white gold and palladium (210).

Before these perfectly smooth plates can be graced by the enameller's brush, they must first be engraved. This process creates a texture and a pattern which scatter the reflected light from the enamel in all directions. The artisan engraver knows it is his job to give the enamel its brilliance, but is also acutely aware that even the slightest error can obliterate it. He therefore works with painstaking care to engrave each palm-shaped recess in the plates, as well as a host of tiny lines which portray the leaf veins and act as reflectors. In addition, he creates a hollow at the centre of each leaf, which emphasises the three-dimensional impression of depth in the final composition.

The enameller hence receives a richly textured set of plates that have required dozens of hours of work already. Using a brush, he drops a very fine mixture of coloured glass and water into each recess or segment, then fires the plates in the kiln at 800°C for a few tens of seconds. The water evaporates, and the glass particles melt and reduce in size; they adhere to the support, creating the colour. The enameller applies several successive layers in order to gradually fill the engraved recesses.

The main challenge of this process is controlling the colour, which darkens as the enamel layers are applied, and achieving this within the constraints of a given thickness. The difficulty therefore lies in finding the precise balance between the set thickness and the perfect colour. To achieve this, the enameller and the engraver had to coordinate their expertise beforehand, learning about each other's craft and the constraints involved, and together redefining the important parameters for the decorative plates.

The result is a fresco of palm leaves and an extraordinary brilliance. The light is reflected off the enamel in as many directions as there are angles and reliefs on the engraved case-back's textured surface. Its colours are intense yet translucent, giving an exquisite impression of depth when the sublime details of the engraving are observed beneath the enamel. The whole composition achieves perfect harmony through the meticulous orchestration of rare shades of blue.

The decoration features both on the Tecnica Palme's dial and on the inside and outside of the double case-back. The motif also appears on the ardillon buckle and on the horns of the case. Finally, the enamel is also in evidence on the watch's hands, where the luminescent coating would normally be applied. In a significant first for the watchmaking world, the skeletonised structure of the hands is filled with a translucent layer of enamel. In this case, with no support from behind, the enamel is applied using the plique-à-jour technique, which requires consummate skill. The hands of the Tecnica Palme form a kind of stained glass window, their delicate colour standing out against the whole composition yet revealing the dial underneath them as they advance. This adds an extra dimension to the sublime interplay of colours that illuminates the piece.

The Tecnica Palme is one of the most complex Haute Horlogerie timepieces, with its mechanism featuring no fewer than four complications. A minute repeater, a chronograph, a tourbillon and a perpetual calendar are housed in a single complete integrated movement. 

The minute repeater is wound elegantly by rotating a knurled ring under the bezel a quarter turn clockwise. This sophisticated activation mechanism represents a challenge in terms of water resistance, as the surface area to be protected from water is much larger than a traditional side bolt.

The white gold case has been designed to ensure that the minute repeater chime has the best possible resonance in an optimal space. In a world where electricity is omnipresent, the minute repeater, which historically enabled the time to be read at night, may seem obsolete. However, the Tecnica Palme's two "cathedral" gongs chime the hours, quarter-hours and minutes with an unrivalled tone which will enchant more enlightened watch lovers.

The movement finishes are exceptional, with all of the bridges hand-engraved. This requires an enormous amount of work both before and afterwards, given that embellishment itself involves deforming the material. All the movement's settings must be checked and precisely readjusted after the bridges have been decorated. High-quality craftsmanship is paramount at Parmigiani Fleurier, regardless of the hours of behind-the-scenes work it requires.

The Tecnica Palme is a tribute to watchmaking expertise and traditional craft skills. The watchmakers who produced it have truly surpassed themselves; it has revived the intricate beauty of engraving and the subtlety of enamel work; finally, it has brought together and intertwined all of these disciplines to achieve aesthetic harmony. 

The result is as precious as a palm tree in the midst of an arid desert.
