Drawing inspiration from the John Arnold pocket chronometer No. 1/36, one of the most historically significant chronometers, Arnold & Son presents the Tourbillon Chronometer No.36 Gunmetal Limited editions
The John Arnold Chronometer No. 1/36 or “Arnold 36” as it is more commonly called was not only the first pocket watch by John Arnold to use a larger movement with his “T” balance, but also the first to be referred to as a “chronometer” for its superior timekeeping capabilities. In this respect, the Tourbillon Chronometer No.36 is faithful, contemporary horological homage.
Weighing mere fractions of a gram, the tourbillon cage consists of no less than 58 components. Prominently positioned on the dial side, the tourbillon can also be viewed from the back, thanks to an opening in the main plate. The same kind of opening is made below the small seconds display, adding to the symmetry of the Tourbillon Chronometer No.36.
The decorative haute horlogerie arts are also lavishly demonstrated in the Tourbillon Chronometer No.36. The entirely in-house conceived and manufactured A&S8600 calibre features a smooth sand-blasted main plate and bridges with chamfered and polished edges. The main plate and bridges are treated with a golden coating, echoing the aesthetics of the historical pocket watches made by John Arnold. The main plate also is set with several mirror-polished 18k gold chatons, while the wheels in the gear train are embellished with circular satin finishing with chamfered and polished edges. Even the screws are beveled and feature mirror-polished heads.
