With a “PROTOTYPE” engraving on the caseback, this piece was likely one of the several prototypes which the brand developed during the early days, to test and experiment different designs. Its vintage-inspired aesthetic is a reminder of where the Franck Muller brand first started.
As shown by the engraving on the caseback, this watch is a prototype piece. In the early days of the brand, Franck Muller was known for producing several stainless-steel chronographs, with a vintage-inspired aesthetic, reminiscent of mid-century pieces. Considering the brand produced several different variations, we assume that this would have been one of the prototypes produced to test a particular design. Typically, prototypes remain within the brand or with employees involved in their creation, so one appearing publicly is always intriguing.
The pared-back, streamlined layout of the dial is a trait shared by many of Muller’s earlier watches, before he became more well-known for his bold and experimental designs. With this piece, Muller draws upon classic elements that can be found on vintage two-register chronographs, combining them with oversized Breguet numerals and a flash of red on the minute track around the outside.
The case is very distinct with its polished, stepped concave bezel and contrasting brushed outer portion. The three-piece construction gives the watch a bold presence on the wrist, measuring 36mm in diameter. Cased in stainless steel, it gives this chronograph a utilitarian and practical aesthetic. The “PROTOTYPE” and “N. 0/0” are engraved into the caseback, in the same style as the “FRANCK MULLER GENEVE” markings, and consistent with other Franck Muller pieces from the same period. Concealed within is a modified Lemania calibre 1874; a reliable and well-constructed movement found in a number of high quality chronographs from the period.

This Franck Muller “Prototype” Chronograph is in good condition overall, with some marks throughout consistent with wear over time. There are more noticeable marks on the bezel (notably between 6 and 9 o’clock), on the polished the sides of the case and on the surface of the caseback. The edge of the caseback and a portion of the main case also displays marks, likely resulting from a previous attempt to open the caseback. The dial, crown, caseback and movement all carry the Franck Muller signature.
The watch comes with a two-year warranty from A Collected Man, alongside a lifetime guarantee of authenticity.
