Arnold & Son TE8 Tourbillon (New References in White Gold & Red Gold)

Arnold & Son unveils two new references of its TE8 Tourbillon in 18-carat white gold & 18-carat red gold versions. Equipped with the hand-finished A&S8000 calibre, the TE8 Tourbillon heralds the Royal Collection that combines classical styling with innovative, state-of-the-art technology. The letters “TE” stand for tourbillon escapement.

Compared with other more conventional tourbillons found today, the TE8’s movement is said to be “inverted”: in other words, most of the technical elements and visually interesting features can be seen on the dial side, when they would normally be hidden away on the reverse.

The timepiece also boasts a number of typically English technical idiosyncrasies that will interest even the most discerning watch connoisseur. Take the symmetrical layout of the movement, for instance: the barrel spring and the tourbillon cage are centred along the watch’s longitudinal axis. The main jewels are hold by screwed gold chatons. They are a reminiscence of the finest Haute Horlogerie mechanical watches of the good old days and contribute to the beauty of the movement.

In addition to their aesthetical appeal, gold chatons also allow to replace damaged jewels without modifying the boreholes in the plates and bridges. A closer examination of the winding system and the gear train reveals a traditional construction used in high-end pocket watches that involves the

use of “wolf-teeth”, an asymmetrical tooth system featuring both long and narrow spokes used primarily to improve the smoothness of the overall movement and to enhance its elegant design.

From an aesthetic point of view, however, the feature that sets Arnold & Son’s TE8 Tourbillon apart is its singularly English design. Some of the more obvious elements include the meticulously positioned three-quarter barrel bridge with its large wave-shaped cut-out and a lavish decoration unique to Arnold & Son, the triangular tourbillon and motion-work bridges, and the three-spoke design of the wheels, which are shaped with such distinctive flair.

Needless to say, every detail of this striking piece, such as the black and brushed polishing, bevelling and movement decoration, is painstakingly hand-finished by Arnold & Son’s master watchmakers.

This unique tourbillon timepiece will be produced in a limited edition of 25 pieces of each version, in a 44 mm 18-carat white gold and 18-carat red gold case with either a movement with NAC grey treated bridges and black ruthenium treated main plate or rhodium treated bridges and NAC grey treated main plate. Each watch case is individually numbered and engraved.

The tourbillon movement, one of the most elegant complications in the world of Haute Horlogerie, 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.
