At the 2019 Salon International de la Haute Horlogerie (SIHH), Chronométrie Ferdinand Berthoud presented a new pillar of its FB 1 collection: the OEuvres d’Or. These were two extremely limited five-piece editions, directly inspired by a creation by Ferdinand Berthoud, the Astronomical Pocket Watch No. 3, assembled and adjusted in Paris in 1806. Today, the OEuvre d'Or collection is enriched by a new limited and numbered edition of five watches (ref. FB 1.2-3), combining a rose gold case with a white gold dial and a movement with three half-bridges in 18-carat rose gold. The overall appearance of the model remains faithful to its inspiration.
