8,7 / 10
Extremely rare model
This specimen is named “No Name” because of its specific dial, with only the NIVADA name and logo, without GRENCHEN, and without the usual 3 lines CHRONOMASTER / AVIATOR / SEA DIVER, and gray sub-dials, explaining also the small hands in black that can be seen more easily.
Note, that as on the other examples of the reference 85017, the caseback is engraved with CHRONOKING.
The watch is in excellent condition, and all its parts are 100% conform.
PLEASE NOTE THAT A COPY OF OUR BOOK “CHRONOMASTER ONLY” WILL BE OFFERED TO THE BUYER OF THIS WATCH.
About the model
The Chronomaster model wasn’t just a chronograph.
It was more like the Super-Chronograph. It in fact had an astonishing number of functions. Such a purpose is accurately reflected in the model’s name: CHRONOMASTER AVIATOR SEA DIVER, which suggests a clientele of professional racing drivers, pilots and divers, as well as the multiple functions evoked in the advertising of the 1960s: THE WORLD’S BUSIEST WATCH – HAS MORE USES THAN EVER COUNTED.
The models fitted with the Valjoux 23 caliber are the third representatives of the Chronomaster dynasty (after the Venus 210 and the Valjoux 92).
This development coincided with relatively major changes to the dial and hands. The dials got new typography for the subdials with simplified scales and the numerals the conventional way up. The broad arrow hands changed to the more contrasting white baton hands, while lollipop, followed by triangular sweep hands indicated the chronograph seconds.
