Bulgari Diagono Champlevé Enamel Dials

Pingtsai delves into Bulgari's intricate Champlevé enamel work, specifically on their Diagono Moonphase and Tourbillon dials, revealing a meticulous four-month creation process. This article highlights Bulgari's evolution towards embodying a true manufacture by combining impressive mechanics with stunning aesthetic craftsmanship. Readers will appreciate the detailed explanation of this ancient European technique applied to modern luxury watches.

Champlevé, Bulgari-Style:  A Four Month Process to Create An Exquisite Dial

Recent watch releases by Bulgari have displayed some of their best dial work to date with intricate hand engraving and miniature hand painting. The efforts have been more than impressive and have added more of a craftsman-like element of appeal to the dials of their watches, giving depth to its traditionally commercialistic approach.

The Serpenti and other tubagos bracelet watches require great skill to create and craft. However the manner in which they were marketed and matched with quartz movements reflected a more commercial approach. With the recently released Commedia Dell’Art and Il Giardino Tropicale watches, matching impressive mechanics with equally stunning aesthetics, Bulgari is finally embodying the meaning of being a true manufacture.  

An Age-Old European Technique

Bulgari continues to expand upon its masterful dial creating skills with Champlevé enamel work, or inlaid enamel, present in the most recent Diagono Moonphase and Tourbillon dials. It is a technique that has been known since ancient times. Champlevé appeared in the West around the 11th century, and was practiced especially in Limoges and Cologne, which became the European centres of champlevé. Beginning in the 12th century and continuing through the rest of the Middle Ages, Limoges was the capital of champlevé enamel on copper, which became extremely popular. Orders poured in from all over Europe.

Champlevé always implies a close bonding between the metal and the coloring substance. The champlevé technique consists of carving cavities into the metal to form the desired aesthetic motif. The design is transferred with a hard lead pencil or dry point engraving tool. The idea is to place the coloring substance in the depressions created for this purpose, the size of which is on the order of a half-millimeter. These cavities are carved with extreme accuracy. Traditional champlevé seeks to achieve a perfectly smooth surface.

A Multi-Step Process for Diagono Dials

The Diagono dials made by Bulgari take four months of work, on average, from the beginning of the process through to the finished piece. After the metal plate is machined to create the cavities, the lacquering phase begins: but first, the colors have to be prepared in just the right mixtures to achieve the desired uniform shades.

Applying the Varnish

Once this step is complete the layers of varnish – about twenty in all – are applied by hand. As soon as each layer of varnish is applied, the piece is placed in the kiln or air-dried to set the lacquer. Though this step may seem simple, it is not. It involves a combination of subtle factors such as firing time, temperature changes, and air-drying time.

Hand Polishing

Then comes hand-polishing, which is very complicated in that it involves smoothing and polishing two very different substances: brass and lacquer. At this stage, the dial must be perfectly flat so as not to cause any dimples in the lacquer filling the cavities. After this long operation come electroplating and transferring, all dedicated to ensuring the perfect quality of this essential element that becomes the “face” of the watch.

Champlevé resembles another way that Bulgari has looked to the past for techniques and inspiration and applied them in a modern way. They have certainly taken enamel dials to a whole new level with their Champlevé technique. One can only imagine what new developments are to be revealed next.
