Jeanneret & Kocher, La Chaux-de-Fonds
House founded by Gérold Jeanneret and E. Kocher in La Chaux-de-Fonds (49, rue Demoiselle). They seem to have been associated between 1893 and 1896. They produce pocket watches with horological complications (Grande Sonnerie, minute repeater, perpetual calendar, chronograph with recorder and split-seconds) and pocket chronometers with bulletins de Marche from the Neuchâtel Observatory. They presented their products at the World’s Columbian Exhibition in Chicago in 1893, receiving a Medal (Unique Medal).

At the Swiss National Exhibition in Geneva in 1896, they were awarded a Silver Medal (Group I, Watchmaking, Section 1, Chronometers and Completed Watches, Cat. No. 59) and a Gold Medal awarded for the Collectivité des Fabricants d’horlogerie de La Chaux-de-Fonds (idem, Cat. No. 28). Gérold Jeanneret was present at the Universal Exhibition in Paris in 1900 (cat. with the design of a watch with horological complications, a triple complication). However, the house was not at the Swiss National Exhibition in Berne in 1914.

In the 1890s, they regularly used ebauches from the manufacturer LeCoultre & Cie, Le Sentier (Vallée de Joux), for their repeater and chronograph watches, but also Louis-Elisée Piguet, Le Brassus (Vallée de Joux), for their watches with Grande Sonnerie. They obtain many bulletins de Marche from the Astronomical Observatory of Neuchâtel; some of their parts are adjusted by Paul Borgstedt (?-?) from Le Locle, Zacharie Pantillon (1844-1929) from La Chaux-de-Fonds, others by F.-E- Thiébaud (?-?) from Geneva.

It should be noted that they obtain bulletins de Marche for watches with horological complications, an extremely rare occurrence, for example, in 1893:

• No. 1 083, minute-repeater, chronograph and perpetual calendar (ranked 43rd in category C).
• No. 1 091, minute repeater, Grande Sonnerie, chronograph and perpetual calendar (ranked 44th in category D).
