Arnold & Sons celebrates 240 years since the creation of John Arnold’s historically significant Chronometer No. 1/36, with two commemorative tribute editions.
The first commemorative edition of the Tourbillon Chronometer No. 36 unveiled last year featured a more traditional English frosted gilt finish on the movement, produced as a limited edition series that immediately become a must-have for aficionados of Arnold & Son timepieces and precision chronometers. The 240th anniversary Tribute Edition of the Tourbillon Chronometer No.36 offers the opportunity to acquire this exceptional and contemporary reinterpretation of John Arnold’s revered chronometer, and thus will be produced as a non-limited production series in red gold and stainless steel models.
Following the classical codes of traditional English chronometer movements, the main pivoting elements such as the wheels, barrels, the tourbillon, and others are each mounted on their own bridge. The triangular, multilevel bridges (no less than thirteen) are mostly skeletonized, providing a more contemporary sense of three-dimensional depth to the entire timepiece.
The tourbillon, a central element of this timepiece, is highlighted in a most magnificent manner. Held by a skeletonized and mirror-polished top bridge, the one-minute tourbillon features a typically Arnold & Son three-spoke design. 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 apparent technical virtuosity of the Tourbillon Chronometer No.36 is not only a treat for the eyes, as the watch is a COSC certified chronometer; something of a rare achievement for a tourbillon-equipped timepiece.
The decorative haute horlogerie arts are also lavishly demonstrated in the Tourbillon Chronometer No.36. The entirely in-house conceived and 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 more contemporary 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. Even the screws are beveled and feature with mirror-polished heads.
The heart of the watch, the tourbillon, features a traditional construction with a top bridge, while the mirror-polished cage has the signature Arnold & Son three-spoke design, making a complete turn in 60 seconds. The double barrels, embellished with laser-engraving decoration, provide a considerable power reserve of 90 hours when fully wound.
