Traditional grand feu enamelling
The Julien Coudray 1518 Manufacture employs this ancient technique for its dials. Hence the centre and indexes of the Manufactura 1528 model are decorated using the champlevé technique: the enamel is brushed into the cavities prepared in solid gold, and then melted at between 800 and 860°C (hence the term "grand feu"). The plique-à-jour technique, an ingenious alternative, employs very thin gold surrounds framing the design patterns. The small recesses obtained in this way are filled with enamel using a brush, and melted at over 800°C. Plique-à-jour enamel filters light like stained glass. The Competentia 1515 model uses these two techniques.
