The new Classique 7147 is one of those emblematic models, imbued with a blend of classicism and tradition, such as only Breguet is capable of producing. It is distinguished by all the refined details composing the identity of the Manufacture since 1775. As on many historical models, the dial of this new creation is made of “Grand Feu” enamel, a magnificent artistic craft.
Although known since ancient times, enamelling was only widely applied to horology from the Renaissance onwards. This extremely complex ornamental technique has remained virtually unchanged since. It is based on a colourless vitreous mixture – called flux – composed of silicic acid, sodium borate, nitre and minium. The flamboyant and ageless colours of enamel are achieved by adding metallic oxides to this combination. The result is subsequently crushed to a powder and humidified to form a paste called barbotine (slip). The latter is applied in successive layers to a metal disc repeatedly fired in a kiln heated to more than 800°C. This process continues until the dial has attained a radiant whiteness and glowing texture. Then comes the transferring of the famous slender, dainty yet legible Breguet numerals, embodying an inestimably precious horological heritage and reminiscent of the early watches and clocks from the House. Hours and minutes are indicated by traditional blued steel Breguet hands with an offset open tip, complemented by the small seconds discreetly sweeping around a 5 o’clock subdial. The splendour of this Classique 7147 is also reflected in its movement, plainly visible through a sapphire crystal caseback and graced with “Côtes de Genève” and “Clous de Paris” hobnailing.
Available in rose gold and white gold versions, this model houses Calibre 502.3SD, equipped with a balance spring in silicon and an inverted in-line lever escapement with horns made of silicon – an extremely light material notably renowned for its non-magnetic properties. It endows the Classique 7147 with remarkable performance and reliability.
