CERTIFICATE OF AUTHENTICITY AND APPRAISAL
1 YEAR MECHANICAL WARRANTY
First produced in 1961 under a partnership between Swiss company Nevada SA and American manufacturer Croton Watch Co., the Chronomaster has exploded in popularity in recent years.
Arguably one of the finest, most versatile tool chronographs from the 1960s, its complicated name (Chronomaster Aviator Sea Diver) reflects a vast number of functions, from chronograph with tachymeter scale and a sailing regatta countdown, to 200m water resistance and a rotating dive bezel, and even a second time zone (on the bezel). Croton/Nivada pushed these features by advertising the watch to the “athletic-minded and the enterprising” and for “versatile” buyers who were “at the centre of events”.
The Chronomaster was produced with a variety of different movements. Reference 107 that we have in the shop today comes with the sturdy Landeron 248 movement preferred by Croton in the North American market from 1966 onward. Since these were outdoor tool watches, finding a good condition Chronomaster can be difficult, but our example today is in spectacular condition, with a superb dial, lume aged to perfection, and a thick, unpolished case with clean bezel.
We have pared it with a hazel Saffiano leather Molequin strap to accentuate its handsome design while at the same time paying homage to its utilitarian roots.
