VC and Chronometer Ratings

 

Thanks Dan smile  Your comments are greatly appreciated, knowing how much of a Chronometre Royal fan you are.  I'm looking forward to hearing about your research on the CR pocket watch chronometer ratings.  An interesting fact that I haven't yet explored was the practice of the Geneva Observatory (and probably others) to issue Chronometer ratings to a series of movements based on testing of a few examples.  I heard this in reference to the Chronometre Royal wristwatches and wonder if it was also the case with earlier CR pocket watch production.
