Hi Buyers!!! You are buying a Rare 1940's Omega Bumper 2491-1 Automatic 17 Jewels Swiss Men's Watch. Pre-owned in good conditions for its age, see pictures for more details as they are part of my description. This watch is working great and keeping time in the last 48hrs. Features a handsome champagne patina color dail with gold arrow markers, sub seconds hands, push-pull original crown, stainless case.I haven't seen another with the same style dail and the 12 marker the way it is. I want to say its a cal.342 but bc it doesn't show it im not 100% sure.  Its a great looking watch, with a new aftermarket band. Normal signs of wear on the rear. Buy with confidence as all my items are authentic. Follow my page as I will be posting more treasures for you to buy every week, thanks.
