In-Depth: A Guide to Every Equation of Time Watch by A.-L. Breguet

Abraham-Louis Breguet (1747-1823) stands among the most revered names in horology, celebrated for innovations that shaped modern watchmaking. While his tourbillon, self-winding mechanism, and anti-shock system are widely acknowledged, his work in astronomical timekeeping, particularly equation of time (EOT) watches, remain one of Breguet’s most intricate yet less-explored achievements. With 2025 marking the 250th anniversary of his birth, this guide offers the most comprehensive study of every known EOT timepiece made during his lifetime, including pocket watch no. 160 “Marie Antoinette”, expanding on our prior analysis of the complication (in parts I and II). No. 160 as pictured at the recent exhibition in London’s Science Museum. Image – Baruch Coutts Looking at the stars Breguet operated in an era where precision timekeeping was dictated by astronomy, and his workshop, positioned at the heart of Paris’s scientific and commercial networks, was uniquely placed to serve scientists, navigators, and royalty who required accurate solar and mean time readings. Rather than settling on a single method for displaying and correcting the EOT, he explored multiple mechanical solutions, refining some while revisiting earlier ideas when necessary. His approach does not follow a strictly linear evolution but instead reflects a dynamic cycle of innovation, mechanical experimentation, and adaptation. Breguet’s cam-driven system with feeler to indicate EOT, as found in pocke...

Auctions: A.-L. Breguet to F.P. Journe at Christie’s Geneva

Rare Watches in Geneva kicks off the spring auction season for Christie’s. Some of the highlights amongst the sale’s 183 lots illustrates the history and evolution of horology, most notably with timepieces by Abraham-Louis Breguet and Francois-Paul Journe. The notable F.P. Journe offerings include a Resonance pre-souscription and a Ruthenium full house, complete with numbered box. The standouts from Breguet include a pocket watch first owned by Pauline Bonaparte, Napoleon’s younger sister, an early striking carriage clock, and an intriguing Type XX precursor literally gone askew. F.P Journe Principally inspired by the work of A.-L. Breguet and Antide Janvier, Francois-Paul Journe’s landmark Chronomètre à Résonance was the first attempt at synchronised, coupled oscillators in a wristwatch. The first numbered 20 examples were reserved for a Breguet-style souscription series – paid in advance by the client – but were not the first made.

About 20 watches starting from “21” onwards are pre-souscription, and this is “041/00R”. Notably, one example prior, “040/00R”, sold for a little under CHF1.4 million including fees at Christie’s in 2023, setting a record.

Recent introductions of the brand focused on compact, retro-inspired watches with a bit less of […]
