A. Lange & Söhne CABARET TOURBILLON HANDWERKSKUNST is – viewed from all sides – an extravagant timepiece. It combines superb watchmaking artistry, to the outermost angles of its rectangular calibre, with elaborate, traditional and, meanwhile, rare techniques. They include semi-transparent enamelling of the dial and several manual engravings in the lozenge design style. The limited 30-watch edition is a special version of the world’s first mechanical wristwatch with stop seconds for the tourbillon as presented by A. Lange & Söhne in 2008.

The CABARET TOURBILLON is a milestone in the history of precision watchmaking. It was with this watch that A. Lange & Söhne succeeded in 2008, for the first time, to instantaneously stop the balance inside the rotating cage – and instantly restart it by pushing the crown home. It is based on Lange’s only rectangular model, which, since its launch, has stood for extravagance as well as for a distinctive movement philosophy: the CABARET. Limited to 30 pieces, the CABARET TOURBILLON HANDWERKSKUNST places special emphasis on its artistic aura. The seventh model of the A. Lange & Söhne HANDWERKSKUNST series launched ten years ago is characterised by the artistic and artisanal qualities of the elaborate finissage of the dial and the movement, with the lozenge chosen as the signature design element.

Combination of traditional craftsmanship disciplines

The three-part dial of the A. Lange & Söhne  CABARET TOURBILLON HANDWERKSKUNST is made of solid white gold and is crafted in the manufactory. The inner area with the typical Lange outsize date is manually engraved with a lozenge pattern. This regular motif sets a challenge to the engraver as every small deviation is instantly visible. It is inspired by the six lozenge-shaped hour markers in gold that face the centre. Together with the Roman numerals III, IX and XII, they stand in the outer zone of the dial with a delicate surface that serves as a stage. A thin line decorated with tremblage visually separates the dial parts from one another. This engraving technique also graces the frame of the hand eye and of the date aperture.

The dial is coated with a semi-transparent enamel layer that adds extra depth to the engraving and showcases various metallic shades of grey. The result is an extravagant dial with a three-dimensional effect.

The separately integrated subsidiary dials for the small seconds and the power-reserve indicator, which at A. Lange & Söhne is traditionally executed with the UP/DOWN display, consist of rhodium-coloured gold; the hands are made of rhodiumed gold. An aperture in the dial reveals the one-minute tourbillon which is suspended between two diamond endstones. On its top side, the matt-finished tourbillon bridge has a black polishing that is applied using a technique that ranks among the most difficult types of finissage.

A rectangular case in platinum measuring 29.5 by 39.2 millimetres forms the precious frame for the new exclusive version of the first tourbillon with a stop-seconds mechanism. It is graced with a deployant buckle in platinum and a black leather strap with grey contrast stitching.

Progress by standstill

The manually wound calibre L042.1 of the A. Lange & Söhne CABARET TOURBILLON HANDWERKSKUNST has a twin mainspring barrel that delivers a power reserve of 120 hours. It is a masterpiece of technology and craftsmanship. It is composed of 370 parts, of which no fewer than 84 are integrated in the filigreed tourbillon that weighs only a quarter of a gram. The movement owes its historic significance to a tiny component that transformed it into a milestone of precision watchmaking.

In 2008, more than 200 years after the invention of the tourbillon, A. Lange & Söhne showed how an oscillating balance inside the rotating cage can be stopped to set a tourbillon timepiece to the precise second. By pulling the crown, a complex lever mechanism is triggered that pivots a movable V-shaped spring onto the balance wheel rim. The balance stops instantaneously, even if one of the spring arms is in contact with one of the three cage posts. The special geometry of the spring assures that the pressure imposed on the balance is always correctly dosed, regardless of the position of the cage. An advantage of this design is that it preserves the potential energy of the balance spring so that the balance can restart instantly as soon as the arresting spring is retracted when the crown is pushed home.

Measuring 22.3 by 32.6 millimetres, the form movement of the A. Lange & Söhne CABARET TOURBILLON HANDWERKSKUNST is tailored to the rectangular shape of the case. In comparison with the 2008 version, it has an indexless oscillation system with a Lange balance spring. The lozenge motif of the dial is echoed by the black-rhodiumed engravings on the tourbillon and intermediate wheel cocks, creating a visual bridge between the dial and the movement side. Simultaneously, the interplay of colours from silver and grey hues initiated on the dial is enriched by a further nuance. The train-wheel bridge in untreated German silver has a subtle granular surface inspired by the movements of historic pocket watches. It accounts for six of the total of nine screwed gold chatons. Two further ones are located on the tourbillon and intermediate wheel cocks, and one is integrated in the tourbillon bridge on the dial side. The winding train, decorated with circular graining, is visibly integrated in the plate. The engraved inscriptions on the plate are black-rhodiumed as well. A limitation engraving on the case back indicates the rarity of the horological masterpiece.
