Jean Mussard Enamel Pocket Watch

Case and Dial Construction

The watch is housed in an 18K gold, two-body 'bassine' case. The reverse of the case is decorated with an enamel painting depicting the mythological scene of Danaé visited by Jupiter, who is represented as a shower of golden rain. The band of the case is decorated with a continuous rural landscape featuring a traveler and a donkey, set against a river background. The dial is composed of white enamel and displays a Roman hour chapter with outer minute divisions marked by five-minute Arabic numerals. The watch is equipped with gold 'Louis XV' hands, matching the material of the case.

The enamel artwork on the exterior of the watch serves as the primary visual decoration. The landscape scenes are executed in a continuous format around the circumference of the case band.

The dial is simple in construction, following early eighteenth-century layouts, focusing on legibility with its white enamel background and high-contrast numerals. The integration of the enamelwork with the gold case indicates a collaboration between a case-maker and an enamel artist.

Movement and Technical Specifications

The movement measures 35 mm, corresponding to 15 1/2 lignes. It is a full plate movement featuring square baluster pillars, which support the train. Power is supplied by a fusee and chain mechanism. The escapement is of the verge type, controlling a steel three-arm balance with a flat spring. The regulation of the watch is handled by a rack and pinion regulator, which operates against a silver plate calibrated from 1 to 6 in Arabic numerals.

The technical components, such as the rack and pinion regulator and the verge escapement, are characteristic features of the watch's construction. The combination of the Geneva-attributed case and the London-attributed movement suggests the interaction of different European horological centers.

Signatures and Provenance

The movement is signed, and the enamel work on the case is attributed to Jean Mussard, who was based in Geneva.

The watch carries an auction-reported provenance, having previously been part of the Lord Sandberg Collection. It was sold in a Geneva auction on March 31, 2001, as lot 10. The current documentation ties the watch to this historical record, providing a trajectory for the object's movement through horological collections since the early twenty-first century.
