I got this Breguet Type 20, 1st Edition this morning, here's an excuse to show them all ;-)
Breguet Type 20, 1st Edition, Ref. Nr. 5101/54
Movement was a Valjoux 222 and from what I've read the case was supplied by Mathey Tissot. (No guarantee for that bit of information)
Made in 1954 and last seviced as seen by the engraved FG (fin de garantie) by the French Military in 06.1980, so it's had a long Mil-flying life ;-)
The dial was sterile on the first batches, changed later, the 30 minute sub dial was also alterd later to 60 minutes.
