Within this context, the Maison has developed a one-of-a-kind creation for this sale, from which the proceeds will benefit research on Duchenne muscular dystrophy: a special Type XXI chronograph, made for the first time in platinum. This model will be on show in Monaco at the end of September before moving on to Hong Kong, Beijing, New York and London. It will end its tour in Geneva, where it will be sold to the highest bidder on November 7^th 2015.

Stemming from the wrist chronographs produced by Breguet in 1935, the first Type XX watches were developed to order for the French military and delivered to its air force and navy from 1954 onwards through to the 1970s. Supplied to pilots as standard issue, the Type XX soon became a cult object much sought-after by aviators. This enthusiasm incited Breguet to produce a contemporary civilian version some years later.

The Only Watch model meets Breguet’s current standards in the field of mechanical horology while featuring a vintage style inspired by its predecessor. This Type XXI 3813 is equipped with the special flyback function featured on the original 1950s model. This complication inherently linked to the field of aeronautics enables instant zero-resetting and restarting of the chronograph counter in one smooth move. 

Another characteristic of this one-of-a-kind model lies in its central chronograph minutes counter ensuring instant readability. The date aperture and 12-hour counter at 6 o’clock also contribute to its time measurement capabilities. This Type XXI chronograph is also equipped with a day/night indicator and small seconds subdial that round off the main functions.

For the first time, the mechanical self-winding 584Q/1 calibre is housed in a platinum case, fitted with a bidirectional rotating bezel. The design of this 42mm-diameter timepiece renowned for its reliability and sturdiness will appeal to a broad audience because of its undeniable authenticity. Its matt slate grey dial, crafted in an exclusive execution for Only Watch, bears stylised Arabic numerals composed of a white transferred base coated with Superluminova. It is enhanced by luminescent hands and hour-markers.

The sporty and sophisticated Type XXI 3813 chronograph in platinum proves itself entirely worthy of its proud lineage: it is a concentrated blend of technical refinement in a reaffirmed vintage style. Fitted with a aged calfskin leather strap, it is delivered, like any great timepiece, in an exclusive presentation box and accompanied by a “unique piece” certificate.
