I always thought that since Zenith had won so many Chronometer competitions that they could use that term on those movements as Chronometer grade but not necessarily each watch having been certified. I’m sure the more knowledgeable here will agree or correct me. Either way, Zenith made some incredible pieces and were, IMO, far ahead of most other companies
Silly old me! I used to believe the propaganda that in order to use words like Officially and certified and superlative and chronometer, the actual movement had to be tested to a standard by some Swiss government laboratory
Apart from the cal. 135, which won five consecutive chronometer competitions, did any other Zenith movement also compete in such a competition?
You would think but I’m sure we’ve all seen those old no names watches with Chronometre on the dial
Yes but it's often the name of the shop, eg it says Patek Philippe Chronometro Gondolo
According to many collectors, the bumper created for Zenith by Ephrem Jobin is superior to all Omega bumpers that have been tested for chronometer certification
