Julien Le Roy Centre Seconds Rack-Lever Watch

This centre seconds pocket watch, attributed to Julien Le Roy à Paris, dates to circa 1800 and is of Swiss origin. The 58 mm diameter timepiece is housed in a contemporary gilt brass case featuring a polished finish and a reeded band. Its dial is white enamel and eccentric, displaying Arabic numerals for the hours and an outer Arabic seconds track. The hinged, full-plate movement is constructed of gilt brass and utilizes a fusee with chain drive. Its primary technical feature is an early form of continental rack-lever escapement incorporating a pirouette, with the spiral spring mounted directly onto the pirouette wheel. This specific mechanical arrangement allows the escapement to beat seconds. The watch is documented in horological literature, including appearances in A.F.A.H.A. bulletin No. 13 and the Uhren Journal für Sammler Klassischer Zeitmesser.

Mantel clock

This mantel clock, created circa 1745–1749, is the work of Parisian clockmaker Julien Le Roy. The object consists of a clock movement housed within a drum-shaped case, which is integral to a larger decorative structure. The case and surrounding elements are constructed from Chantilly soft-paste porcelain mounted on a gilt bronze base. The aesthetic design incorporates numerous flowers rendered in both soft- and hard-paste porcelain, interspersed throughout the bronze branches that support the clock housing. The assembly rests on a stylized gilt bronze base and features a porcelain figure of a seated deity.
