Ferdinand Berthoud

Ferdinand Berthoud was born on 18 March 1727 in Plancemont, near Couvet, in the Val-de-Travers district of the canton of Neuchatel, Switzerland (Encyclopaedia Britannica gives 19 March 1727, a minor discrepancy against the consensus of other biographical sources). He apprenticed under his older brother, the clockmaker Jean-Henry Berthoud, in Couvet from 1741 to 1745, receiving a watchmaking and clockmaking apprenticeship certificate on 13 April 1745. That year he moved to Paris to continue his training among the city's watchmakers, and in 1753 he was granted the title of master clockmaker there.

Berthoud built his reputation on marine chronometers and other precision timekeepers, work that led to his appointment as Horologist-Mechanic to the King and to the Navy of France. His scientific standing grew alongside his craft: he was elected a foreign fellow of the Royal Society of London in 1764 in recognition of his horological writings, and in 1795 became a resident member, First Class, of the Institut National de France. In 1802 he published Histoire de la mesure du temps par les horloges, a major treatise on the history of timekeeping. On 17 July 1804, Napoleon Bonaparte named him a Knight of the Legion of Honour as a member of the Institut.

Ferdinand Berthoud died on 20 June 1807 in Groslay, near Montmorency north of Paris, at the age of 80, and was buried there. He left no children.

No exact, attributable quotations from named critics in major general-interest or art-world outlets were located in current research; most substantive commentary on Berthoud comes from horological scholarship, encyclopedia entries, and institutional histories rather than art criticism in the conventional sense. Within that literature, the consistent framing is of Berthoud as a leading Enlightenment horologist and researcher: his election to the Royal Society was explicitly tied to the importance of his published writings, and his standing was reinforced by membership in the Institut National de France and, later, the Legion of Honour. Current research did not confirm the details of any dedicated museum retrospective devoted to Berthoud, though his instruments remain part of major museum collections, including the Metropolitan Museum of Art, which continues to represent his standing in the history of precision timekeeping.

Current research did not surface a reliably documented, well-sourced auction record for an authentic eighteenth-century instrument made by Ferdinand Berthoud himself; scattered secondary mentions of historical Berthoud pieces at auction could not be confirmed with sufficient sourcing to report a specific price here.

Separately, a contemporary watch brand named Chronometrie Ferdinand Berthoud, part of the Chopard Group and relaunched in 2015 under Karl-Friedrich Scheufele, produces new watches that invoke his name and legacy. One of these, a unique stainless-steel piece called Naissance d'une Montre 3, sold as a charity lot for CHF 1,270,000 (reported by one outlet as approximately CHF 1.3 million) at a Phillips Geneva watch auction in November 2025; the exact calendar date of the sale is not confirmed in current sourcing. Trade press described the result as a record for the modern brand at auction. This figure applies to a piece made in the 2020s and should not be read as a price for an original object made by the historical maker, who died in 1807.

There is no catalogue raisonne for Ferdinand Berthoud, and current research did not confirm a reliable, well-documented auction price record for an authentic historical piece by his hand, so provenance and comparison to catalogued museum examples, rather than a clean price history, are the practical basis for evaluating any object offered as his work. Collectors should also take care to distinguish the historical maker, who died in 1807, from the unrelated contemporary watch brand Chronometrie Ferdinand Berthoud, part of the Chopard Group since 2015, which uses his name on newly made watches; the two should never be treated as the same market. Given how thin public data is for genuine eighteenth-century Berthoud instruments, any single reported sale should be treated with caution rather than as evidence of a broader price trend.
