Arnold & Son celebrates 240 years of chronometers with latest hefty watch


Arnold & Son has created another timepiece to celebrate its trailblazing history, as the brand clocks up over two centuries in business. 

The 240th anniversary tribute edition of the Tourbillon Chronometer No.36 boasts itself as a “contemporary reinterpretation” of John Arnold’s chronometer, the Arnold 36, which was the first timepiece to be seen as a chronometer.

The 46mm skeletonized piece boasts a central hour and minutes, as well as an exposed small seconds subdial at the 6:30 position and the tourbillon function off-centered also. The timepiece also sports 90 hours of autonomy.


The tourbillon features a traditional construction with a top bridge, while the mirror-polished cage has the Arnold & Son three-spoke design, making a complete turn in 60 seconds.

Meanwhile the in-house manufactured A&S8600 movement features a lightly grained sand-blasted main plate treated with a main plate in NAC grey in the red gold version, while the steel version has a black DLC surface.

The bridges are satin-brushed with chamfered and polished edges, and are done in a lighter palladium tone on the red gold version, and NAC grey in the steel version. The main plate also is set with several mirror-polished 18k white gold chatons, while the wheels in the gear train are embellished with circular satin finishing with chamfered and polished edges.

The chronometer comes with a black or brown alligator strap.
