For sale: Omega 'ultra-flat automatic' 2374/5 35mm crown excluded 1946 no box or papers bombproof fully insured shipping is 15 to 35 euro, express delivery (24 to 48h is 65 euro) Omega in-house bumper cal. 30.10 RA Asking 1150 euro net to me Lovely Favre Perret cased two-tone 2374 with thick radium on the dial (and in the hands). It has some history on the forum here already. The dial is beautifully preserved with nice even patina. The case is unpolished and sharp, and shows correct radial brushing on the lugs. This piece is completely original, up to the unsigned crystal and the signed 'bulb' crown. It is a great reference with the special waterproof case sealed with a notched ring, and a design said to be the flattest automatic produced in series during the 1940s. Note that the crystal is showing slight crazing. The service history is unknown but the watch runs well and keeps time. The movement is very clean and unspoiled. The watch is sold head-only. The lug size is 18mm. Pictures!
