Congratulations with a nice Breitling Premier!
The Premier without date was made
in 1997/1998, it was also made with date in 1999.
The Premier was based on the 37 mm Navitimer case and used a Kelek cal. 10000/Breitling B40 movement, made especially for Breitling with 3 hours/10 minutes chronograph registers. Kelek made the movements based on a highly modified ebauche from ETA.
Breitling made about
5000 in stainless steel and about 1000 in red gold.
I have the model with silver dial.
Best Regards
Livius
