Henri Jacot No. 8920 Carriage Timepiece

Partially verified

This carriage timepiece is attributed by the source dealer to maker Henri Jacot under number 8920, dated to circa 1890. Housed in a brass corniche case with a folding overhead carrying handle, the clock features a rectangular white enamel dial set with black Roman numerals and blued steel hands. An oval bevelled glass viewing window set into the upper plate allows observation of the platform escapement, which the dealer describes as an original lever platform. Dealer measurements record a height of 7 inches (18 cm), a top width of 4 inches (10 cm), and a top depth of 3.25 inches (8 cm).
