1925 Urra Chronometre Watch
1925 Urra Chronometre, enamel multi-scale dial, simgle pusher Chronograph cal. Hahn. I’ve seen the same dial labeled Rex and Breitling.
Charles Hahn bought Anatole Breitling’s patents and started making chronograph movements around 1925, so this movement shows clearly its Monbrillant ancestry.
