Official description

Only 20 examples of the new Régulateur Squelette movement will be produced and housed in a choice of round or octagonal cases.

The calibre FB-T.FC-RS with tourbillon and fusee-and-chain transmission thus heralds a new approach for Chronométrie Ferdinand Berthoud, enabling collectors to appreciate the rarity of precision mechanics while choosing the case design that suits them best.

It would have been inconceivable, almost three centuries ago, for someone to acquire a pocket watch or clock not entirely made to match one's personal taste. Over time, this consideration gradually ebbed away, replaced by standardisation as watches became widely distributed products. Nonetheless, this approach, which enabled watchmaking to flourish in an unprecedented way, does not fully correspond to the spirit of Chronométrie Ferdinand Berthoud.
