Timeless elegance, handcraft and innovative technology: Arnold & Son's TE8 Tourbillon Métiers d'Art I

True to English watchmaking and handcraft heritage, Arnold & Son unveils the TE8 Tourbillon special edition Métiers d'Art I, limited to only eight exclusive timepieces. This latest special edition to the Arnold & Son Royal Collection is an eloquent expression of elegance and sophistication in the inimitable English style and demonstrates the brand's traditional prowess in the classical decorative arts.

The tourbillon movement, one of the most elegant complications in the world of horology, has played a crucial role in Arnold & Son's history. An exceptional watchmaker, John Arnold was an active participant in one of the most extraordinary partnerships in the world of innovative horology. Indeed, both he and A.-L. Breguet worked closely, sharing both their knowledge and passion. Evidence of their partnership is A.-L. Breguet's first ever tourbillon mounted in John Arnold's No. 11 movement, a watch that can be found today in London's British Museum.

Each single TE8 Tourbillon Special Edition Métiers d'Art I is hand-engraved by Arnold & Son's own master engraver, who went as far as to create a new engraving pattern solely for this special edition. This new pattern is composed of complex geometrical elements arising from the center of the movement. The engraving of this masterpiece is particularly painstaking as the movement is made of German Silver and not usual brass. Due to the hardness of German Silver, the engraver must pay great attention not to slip off and constantly sharpen his tools, as their wear and tear is very high,

Hand-engraving is a traditional art form that involves the use of hardened steel tools called burins in combination with other special tools. These create cuts, lines and texturing that build up entire images or, as in the case of the TE8 Tourbillon Special Edition I, a beautiful hand-engraved pattern on the barrel bridge and on the back of the main plate, bringing a breathtaking richness of detail to an already exceptional tourbillion timepiece.

The Arnold & Son's Tourbillon TE8 movement design is considered unique in it's "English" design: the dial is a ¾ wave-form cut-out on the barrel bridge, the tourbillon and motion-work bridges are triangular, and even the three-spoke wheels are shaped with a distinctive flare. This same three-spoke design can also be found in the tourbillon cage as well.

When compared to more conventional tourbillons found today, the TE8 model is said to be "inverted", that is to say most technical elements and visually interesting features are shown on the dial side, when those would normally be hidden on the reverse of the dial. Other typically English technical idiosyncrasies will seduce even the most demanding watch connoisseurs. Take, for instance, the symmetrical layout of the movement; to achieve such a feat requires overcoming a number of technical challenges. Thus the barrel spring and the tourbillon cage are centered along the watch's longitudinal axis. When examining the winding system, one notes the traditional construction, which uses wheels with long and narrow spokes known as wolf's teeth, used to improve the smoothness of the overall movement.

It goes without saying that every finishing touch on this striking piece, with such beautiful craftsmanship in the hand-engraving and the movement decoration with manually chamfered bridges and polished edges has been done by hand by Arnold & Son's master watchmakers, thus bringing more brilliance and depth to each decorative element to the tourbillon movement design.

This unique timepiece will be produced in a limited edition of 8 timepieces, in a 44 mm 18-carat rose gold case with each movement, individually hand-engraved and numbered.
