Arnold & Son celebrated its double tourbillon series, launching two unique pieces, decorated with dazzling green emeralds and exquisite white opals. The two independent tourbillons and two time zones of this rare model have been renewed, and are available in red gold or platinum.

Press release information and additional information and comments in italics.

Arnold & Son Double Tourbillon is a very interesting watch. Its symmetrical layout of the double tourbillon is proudly displayed on one side of the dial, and there are two sub-dials that display dual time zones next to it. We detailed this watch in our comprehensive review: Arnold & Son DTE 2015. In that comment, we said: “We think Arnold & Son has made great strides. With the support of Citizen, we have seen more mature strategies and implementations, resulting in very interesting and well-thought-out watches such as DTE." In fact, in the following years, we have seen Arnold bravely defending the fine watch industry under the ownership of Citizen. It is remarkable because the Japanese giant has shown considerable restraint, not interfering with the Swiss mentality and working methods that would destroy DNA. However, the British DNA in Swiss-made watches continues to flourish. DTE (Dual Tourbillon Escapement) is classified by Arnold & Son as an advanced complication, so the price is high, but when we checked the 2015 version, we thought it was up to the standard.

The double tourbillon not only demonstrated a high level of design ability, but also demonstrated La Joux Perret's ability to perform fine processing. The dial is very symmetrical on the 12/6 axis and has a time zone. For example, the local time is displayed on a sub-dial marked with Roman numerals at 12 o'clock, and the sub-dial at 6 o'clock can be set as an alternate time zone marked with Arabic numerals. . Each time zone has its own setting mechanism, which can be set independently to the minute, completely independent gear train and tourbillon.

To say the least, the choice of emerald dials is unusual. Being able to offer an emerald dial at a premium of only 10,000 Swiss francs is a fairly reasonable ransom. The visual aesthetics are so beautiful that we want to know why this mineral is not often used in the fine watchmaking industry. Perhaps cutting and processing are quite difficult. But the burst of bright green nephrite against the shiny bridges of the twin tourbillons is quite beautiful. The movement is also very hardcovered, offering a level commensurate with the high asking price.

We look forward to handling and photographing the watch when it arrives on the coast of Singapore. We hope that soon. And will bring you a comprehensive hands-on review when we do.

The global retail price is 198,000 Swiss francs, subject to change (excluding tax). Compared with the German silver dial with Geneva stripes, the emerald dial is 10,000 Swiss francs more expensive.

Arnold & Son continues to make progress in the field of excellence and unique work. The double tourbillon jade is also consistent with the brand's series, and the dial is decorated with expressive rare gems.

Arnold & Son’s watchmaking industry has now taken a step forward in terms of uniqueness and symbolic power, producing two unique versions of double tourbillon models, with a green emerald dial and two immaculate white opal sub-dials. . The A&S8513 movement allows its two independent tourbillons to emerge on these rare gems. Consists of a shared motherboard, each showing a different time zone.

Arnold & Son, the mineral beauty, set his sights on the jadeite in Wyoming. This bright green nephrite called "apple green" has black veins. This brings greater depth, contrast and makes the stone more precious. Jade itself is a kind of stone with rich symbolic meaning. A mineral related to the sacred beliefs, traditional medicine and conservation rituals of Asian and Central American civilizations; its cultural significance makes it unique.

The dial of the Double Tourbillon Jade watch is professionally cut in a very special way. The main bridge is in the shape of a clover, allowing the dial and tourbillon to fully display. This complicates the stone cutting and engraving stages, which further highlights the mastery of the work.

The second major area of ​​expertise of Arnold & Son is reflected in the movement. The double tourbillon jade movement is integrated in a red gold or white gold case with a diameter of 43.5 mm. Its sapphire crystal mirror is dome-shaped and can accommodate the height created by two tourbillons. They are attached to a three-dimensional, hollow cantilever bridge and are made of the same gold as the case. They are the pinnacle of Arnold & Son's ability to design, manufacture, finish and adjust.

Duality Arnold & Son pays tribute to its founder John Arnold. John Arnold is one of the most creative watchmakers of his time and the golden age of timing technology. Arnold & Son has always approached dual time zones with precision and precision. Different from the classic "GMT" system, the hour hand in the center indicates the second time zone. Arnold & Son chooses to equip each time zone with its own adjustment mechanism: to remind the duality of the time telling method-the timepiece is on the other hand, astronomy ——Used on British frigates in the 18th century.

Therefore, the A&S8513 movement is equipped with two barrels and two crowns that control two time zones. At noon, the local time is displayed in Roman numerals. The Arabic numerals at six o'clock indicate the time of the second, more distant place related to the wearer. The two time zones are set completely independently, accurate to the minute. Unlike most so-called travel watches, the emerald double tourbillon can therefore be offset by 15, 30 or 45 minutes following the time zone, as is the case in some countries in Central Asia.

The structure of the exquisitely finished movement can be seen on the back of the double tourbillon jade. The extremely successful finishes of the Arnold & Son watchmaking profession have reached the highest level. From the radiant Geneva waves to the circular texture on the main board, the double snail-shaped barrel, the sun pattern decoration on the crown wheel, and the polishing of the gold bezel fixed by blue screws, everything about the A&S8513 movement is exuded With outstanding charm, craftsmanship and excellence.
