About the Arnold & Son Grandes Complications Collection

The Advent of Grandes Complications

Amongst the collections under Arnold & Son, one collection holds the distinction of being unique, The Grandes Complications. The Arnold & Son Grandes Complications collection is an amalgamation of various limited edition timepieces celebrating the Grandeur of Arnold & Son. Be it the Double Tourbillon in Jade and Red Gold or the Constant Force Tourbillon, the timepieces were deployed under different collections. With the reshuffling of the collections, it was needed that Arnold & Son preserved the unique and complicated timepieces that were important to their heritage. This is where the idea of Grandes Complications came in.


Under the Arnold & Son Grandes Complications collection, the Double Tourbillon series is fitted with two dials placed at 12 and 6 o’clock. Whereas, the two tourbillons are set at 3 and 9 o’clock markers. The sub-dial of the Double Tourbillon is white lacquered and placed over a dial made of rare materials like Jadestone in some timepieces. Inside the Constant Force Tourbillon series, the small seconds are placed between the 7 and 8 o’clock marker and the tourbillon is fitted between the 4 and 5 o’clock marker. Whereas, with the Tourbillon Escapement Sapphire, the tourbillon is fixed at 6 o’clock.


The movements inside the Arnold & Son Grandes Complications collection are not uniform as the collection is comprised of different timepieces. Nevertheless, the collection is fitted with movements such as A&S5119, A&S8513, and A&S8100.

Arnold & Son Constant Force Tourbillon


From the family of marine chronometers, the Arnold & Son Constant Force Tourbillon approaches the world of chronometry in a trifold manner. The Constant Force Tourbillon has a robust manual-winding movement, the A&S5119. The A&S5119 is known for providing constant torque which is further translated to accurate timekeeping even when the power reserve reaches the end of its cycle. Moreover, it provides a power reserve of approximately 90 hours while vibrating at 21,600 vph.
