Flash News: Arnold & Son Double Tourbillon Escapement Dual Time

By Thierry Ané on March 5, 2014

Unfortunately, I only have a single official picture (for now!) of Arnold & Son’s new Double Tourbillon Escapement Dual Time and only a few technical characteristics to help me write this short article, but the watch is too amazing for me to wait until Baselworld to introduce it to you!


As part of the celebrations for its 250 years of watchmaking history, the Swiss brand with a unique English heritage has just unveiled the Double Tourbillon Escapement Dual Time model that will be produced in a limited run of 28 pieces.


Part of the “Instrument Collection”, this extremely elegant timepiece is housed in a highly polished 43.5 mm red gold case quite similar in shape to the brand’s previous creations. It is mounted on a brown alligator strap secured by a traditional red gold pin buckle.


But a mere glance at the dial lets you know immediately that this is no “ordinary” watch (if “ordinary” can ever apply to a timepiece produced by this insanely creative brand!). The first thing you will notice is the extraordinary symmetry of the elements on display. On the vertical axis, you will find two domed white lacquered sub-dials at 12 and 6 o’clock. The former with Roman numerals and the latter marked with Arabic numerals. Both of them feature beautiful blued steel hands with hollowed arrow heads. On the horizontal axis, two tourbillon escapements face one another in perfect symmetry at 3 and 9 o’clock. The geometry of this design is cleverly enhanced by the extremely refined vertical “Côtes de Genève” motif on the base plate.


Animating the watch is the all-new mechanical hand-wound A&S8513 calibre that brings the centuries-old tradition of double movements back to life. It features two time zone displays entirely independent from one another. Unlike most dual time zone models on the market, this watch can indicate any time difference between “local” and “home” times, as each time zone can be set to the nearest minute: with the crown at two o’clock for the “local time” and through the crown at 8 o’clock for the “home time”. Each has its own gear train and tourbillon escapement but a common impressive power reserve of 90 hours obtained by two mainsprings that are wound using the crown at 2 o’clock.


This exclusive timepiece features a sapphire case back that offers an opportunity to marvel at the superlative Haute Horology finishing the brand is so accustomed to. Unfortunately we don’t yet have a single picture of the case back, or of the movement for that matter. For now, we will thus have to trust the brand when they say that this nickel-silver movement has been “rhodium-treated with hand-chamfered bridges and polished edges” and that it features “fine circular graining and Côtes de Genève rayonnantes”. But since these are the exacting standards Arnold & Son has set for itself with previous models, there is no doubt that the back of this watch is as astonishing and beautiful as the dial side.


In a nutshell, the brand continues to create outstanding timepieces true to its historical roots in terms of aesthetic elegance and quest for mechanical perfection. I really can’t wait for my Basel appointment with Sébastien Chaulmontet, the brand’s Head of Movement Development, to find out more about this exceptional timepiece and the rest of their novelties that will undoubtedly be equally stunning. I will come back on this impressive brand with live pictures and additional information during Baselworld.
