After finding out that my last years auction find needs a proper revision, I decided to send it to Longines HQ in St. Imier for inspection.
Originality of dial, case and movement already confirmed by their vintage department, watch now is headed for service incl. certificate of authenticity. Will take some months but very much looking forward! 😀
I know it's not the 12th today, but this is still the dial that gives me the most pleasure of all.
