The Gaumont Chrono de Poche is an early French pocket-format camera, dating from the late 19th / early 20th century period when Gaumont was active as a manufacturer of photographic and cinematographic equipment. It was designed as a compact instrument for plate photography, positioned at the more portable end of the era's apparatus.

Auction data for the Chrono de Poche is extremely thin: a single recorded UK saleroom result from 2004 saw a hammer price of £2,390, which is the only reliable reference point for what one is worth today. With just one wholesale auction sale on file, no meaningful range or median can be quoted, and the price a comparable example sells for in the current market would depend heavily on condition, completeness and bidder competition on the day.
