The Reference Number
The reference above the serial on the caseback of the regattas (in the years 1958-1974) shows these infos:
First two digits shows the movement: the 87 stands for the Certina 29-064, a Valjoux 728
Second two digits stands for the case material: here 01 for a steel case
Last three digits indicate the appropriate model or the case style – 5o4 stands for the Chronolympic “Regatta” Chronograph
Here you can see 4 types of dials for this regatta watch. They might be test dials because on is withouth brand or logo.
The paintless wonder dials
As we know from some Heuer watches with blue dials the color can change with the time, so seen on the blue Monaco or Carrera BN and some others. We have seen 2 watches with color change and some loose dials on ebay from time to time.
The Ebauche logo on the dial
Eska on the dial
Ulysee Narding Chronolypic – unique watch on custom demand or built together?
There is just a found on the web, only this one watch. So maybe it´s just put together in a case with printed the logo on a clean dial or it might be real?
We still believe in count 3 to make a series. Would love to hear your opinion, if there are any UN expert knows something.
