Enamel Polish: Intricately crafted grand feu dials take timepieces into another dimension

Enamel timepieces represent some of the most elegant and beautiful models available in the high-end watch market. The process of constructing an enamel dial is time-consuming and expensive. It involves fusing soft glass – usually made from silica – onto a metal substrate in an oven heated to about 800°C – hence the term grand feu enamel – and delicately applying layers of enamel powder by paintbrush onto a wafer-thin metal disc.


It is a temperamental material that may emerge from the oven with imperfections. Successive coats and multiple firing cycles are required for a uniform surface – the need for five or more layers of enamel is usual. Yet, the watch dials can be just a millimetre thick, if not thinner. The craft takes years of practice and often renders each dial unique.


A fine example of a dazzling enamel watch is Vacheron Constantin’s recent addition to its Métiers d’Art collection. Tribute to Explorer Naturalists embraces, in fact, four models each released in 10-piece limited editions and designed as a tribute to the scientific discoveries of the Voyage of the Beagle in the early 1830s. The dexterity of the master engravers and enamellers comes to the fore in the aesthetics of richly decorated grand feu miniature enamel dials displaying scenes from four locations along the coast of South America, where Charles Darwin encountered previously unknown plants and animals.


Encased in a 41-mm diameter 18-carat white or pink gold case and featuring a jumping hours and minutes display, each scene took a master enameller four days of meticulous craftsmanship to compose, using fine pigments on a two-level dial. For instance, the white-gold Cap-Vert model concentrates on the Cape Verde stop (January 1832), with the upper dial displaying the HMS Beagle in the centre, viewed from the stern, while the lower dial on the right enthrals with a montage of colourful flowers and luxuriant foliage.


Breguet’s Classique Dragon 7145 celebrates the Chinese zodiac with the powerful dragon exotically embellishing a distinctive dial composed of red grand feu enamel with gold applied – a perfect combination to bring out the majesty of the auspicious creature. Utilising a Calibre 502.5 self-winding movement housed in a rose-gold case, the watch is limited to eight pieces and blessed with a power reserve of 45 hours.


Chopard often calls upon the power of the enamellist to highlight the aesthetic qualities of a watch. Take its Imperiale in 18-carat ethical white gold, which has two enamel colour tones gracing the dial. Most noticeably, a deep, luscious blue-green enamel sets the tone of this feminine watch, which is encircled by white enamel-filled arabesques formed out of a raised white-gold decorative fillet. Its elegance is enhanced by a shower of padparadscha sapphires, diamonds and mother-of-pearl, as well as gilded openwork dagger-shaped hour and minute hands. A seamless alligator strap in blue-green or pink comes with a white-gold buckle set with diamonds.


Representing a first for the minimalist Louis Erard Le Régulateur model, an edition just off the blocks has a dial made with grand feu enamel. Unlike a traditional dial, an enamel dial comes without the risk of fading and the unalterable hue here is a slightly speckled ivory colour. It is the handiwork of the Donzé Cadrans workshop in Le Locle, Switzerland. The hours counter at 12 o’clock and the seconds counter at 6 o’clock come in two-colour enamel detail, fused together by the final firing. Crafted in polished stainless steel and measuring 39 mm in diameter, Le Régulateur Grand Feu Enamel is limited to 99 pieces, underscoring the exclusivity of enamel-dial watches.


Dedicated to métiers d’art, Geneva-based Taos has a range of one-of-a-kind watches that employ the luxuriousness of enamel. The Euphorie is dressed in a grand feu paillonné enamel dial, achieved through a multiple overlay of gold and silver paillons and enamel emanating from multiple firings. Its bold colour code comprises red, orange and black. The self-winding VOP318 calibre movement was developed exclusively by Swiss manufacturer Télôs for the independent watchmaker. The pretty Floréal model has a silver, blue and pink dial with a miniature flower painting etched out of mother-of-pearl placed on paillonné enamel. Delightful petals are formed out of cloisonné enamel.


The pink-gold Reverso Tribute Enamel ‘Dragon’ timepiece was released by Jaeger-Lecoultre in homage to the ancient crafts of enamelling and engraving. Both the dial and case back are composed of grand feu enamel in such a pure black hue that they required five or six layers of enamel to ensure the depth of colour is retained. This was a lengthy process as each new layer necessitated another round of firing and cooling – meaning the process took many days, eventually culminating in a half-day of polishing. Other notable features include the dragon etched out of pink gold and set among golden clouds on the reverse side of the case and the Jaeger-LeCoultre manually wound Calibre 822 movement.


Limited to 50 pieces, Blancpain’s Villeret Traditional Chinese Calendar entered its second 12-year cycle this year with a new addition utilising full-fired grand feu enamel for its dial. Marking a first for this unique grand complication series that boasts both a complex Chinese calendar and a Gregorian date and moonphase, it pairs red gold with a green enamel dial for a striking colour code. The patented under-lug correctors that facilitate finger-tip changes of the calendar are also worthy of remark. Another nifty mechanism protects from damage if settings are adjusted during automatic changes.


Cartier’s latest Crocodile Jewellery watches utilise the aesthetics and magical beauty of enamel to full effect. Graded enamel is used to recreate a sculptural creature in the guise of a crocodile which coils menacingly around the case and dial. The crocodile’s bright emerald eye, its scaly skin and slick curves crafted from enamel portray depth and realism and harmonise with the hues emanating from diamonds and gemstones adorning the timepiece. Besides a crocodile and a crocodile-cum-zebra, there are numerous other iterations of these bewitching, bejewelled animal watches that cannot fail to capture the imagination.


Seiko’s Presage SPB403J1 model in the Craftmanship Series features an enamel dial as part of its attributes, wedged in a 40.2-mm case made of stainless steel with super-hard coating. Its dual-curved sapphire crystal glass is daubed with anti-reflective coating on its inner surface. Powered by a 6R55 automatic manually wound movement with a power reserve of 72 hours, it is water resistant to a depth of 100 metres and has a see-through case back.
