Constant Force Tourbillon combines a patented constant-force mechanism, true-beat seconds and a tourbillon in a chronometry-focused architecture inspired by John Arnold's precision instruments.
Open family lineage in The Dial Atlas
The Arnold & Son Constant Force Tourbillon lineage currently brings together 2 cataloged references spanning 2025. It is organized around exact reference identities so changes in case size, materials, dial execution, movement, and production status remain visible instead of being flattened into one broad model name.
Records surfaced on this page include Constant Force Tourbillon 11 Platinum 1FCBX.Z01A.C0232X and Constant Force Tourbillon 11 Yellow Gold 1FCBJ.E01A.C246J. The list favors entries with usable imagery before continuing through the family catalog, while the sitemap preserves a discovery path to every published reference page.
Use the reference links to move from the family overview into individual dossiers. Depending on the available source material, those pages can document reference codes, production years, nicknames, variants, images, and current or discontinued status. The interactive Atlas view adds visual browsing, while this crawlable page keeps the underlying lineage accessible to search engines and readers using ordinary web navigation.
