ARNOLD & SON – GRAND COMPLICATIONS Double Tourbillon JADE Gold Unique Pieces 2021
Arnold & Son is celebrating its Double Tourbillon collection with the unveiling of two unique pieces adorned with dazzling green jade and delicate white opal – Arnold & Son Double Tourbillon Jade. The two independent tourbillons and two time zones of this rare model have taken on a new face. The result of high-calibre watchmaking execution, these models are available in either red gold or white gold.

Arnold & Son’s watchmaking has now climbed up a notch in singularity and symbolic strength, producing two unique versions of its Double Tourbillon model with a green jade dial punctuated by two opal sub-dials in immaculate white. The A&S8513 calibre allows its two independent tourbillons to emerge into view above these rare stones. United by a shared main plate, each displays a different time zone.
A mineral beauty
Arnold & Son had their sights set on jade from Wyoming. This bright green nephrite known as “Apple Green” is slightly veined with black. This brings greater depth, contrast and makes the stone all the more precious. Jade itself is a stone rich in symbolic meaning. A mineral linked to sacred beliefs, traditional medicine and protective rituals of several Asian and Central American civilisations; its cultural significance makes it like no other stone in the world.

Watchmaking excellence
Arnold & Son’s second major area of expertise is demonstrated by the calibre. The Double Tourbillon Jade movement is integrated into a red gold or white gold case with a diameter of 43.5 mm. Its sapphire crystal is domed, accommodating the height created by the two tourbillons.

These are attached to a three-dimensional, skeletonized, cantilevered bridge, and are made in the same gold as the case. They are the culmination of the design, manufacture, finish and adjusting capabilities of Arnold & Son.
Duality
Paying homage to its founder, John Arnold, one of the most inventive watchmakers of his time and of the golden age of chronometry, Arnold & Son has always approached the double time zone with sophistication and precision.

Instead of the classic “GMT” system, where an hour hand in the centre indicates the second time zone, Arnold & Son has chosen to give each time zone its own regulating organ: a reminder of the duality of time telling methods – timepieces on one hand, astronomy on the other – used on board English frigates in the 18th century.

The A&S8513 calibre is therefore equipped with two barrels and two crowns that control the two time zones. At midday, the local time is visible in Roman numerals. At six o’clock, Arabic numerals indicate the time of a second, more distant place that has a connection to the wearer. The two time zones are set completely independently down to the minute.

Refined finishes
The structure of the movement can be seen on the back of the Double Tourbillon Jade. The extremely successful finishes, a specialism in Arnold & Son watchmaking, are taken to the highest level.
