Here for sale is a nice manual winding steel cased Omega 2791 with a 30mm calibre 266 dating from around 1955 The ref 2791 has a substantial 36mm sized case with very nicely defined lugs and a snap back waterproof case. My example is in fine, and IMO unpolished, condition. Unsigned crown. The off white/creamish dial is attractive and has aged pretty evenly with a couple of small stains here and there. The radium arabic markers and steel pencil hands are crisp and corrosion free. The calibre 266 is winding smoothly, setting and running very well although I have no service history for this one. Selling head only at €695 net to me which is including worldwide Track and Trace shipping. Payment options are bank transfer or PayPal for established forum members only. Any questions just ask
