Adolphe Nicole, Patent No 10,348 of October 1844, includes the first commercially successful keyless work for the ‘heart shaped cam’ controller for true, start/stop/return to zero, chronographs (and timers). Joined by Danish born watchmaker Emil Nielsen, becoming Nicole Nielsen & Co by 1876, the firm were the foremost London watchmakers of the second half of the 19th century, supplying many of the finest chronographs, repeaters and tourbillion watches to retailers such as Frodsham, Dent, Smith & Son, etc.
NB: NN also produced timers, although examples are rarely seen, and this is almost certainly of their manufacture. It is an ideal accompaniment for a watch worn with a double Albert, and often more convenient in use than a true chronograph (a watch & timer combined)
Faint hairline crack in the dial, otherwise almost as new. Serviced and guaranteed.
