A magnificent watch! The serial number dates this one to 1944, and look at the state of it! I have replaced the crystal and one arm for the reset pusher witch was broken. The pusher itself is the original. Everything is in full working order and the watch keeps time flawlessly. New Hadley Roma leather band and stainless steel deployment clasp. If you are reading this you probably already know that this is a column wheel chronograph mechanism. The shiny plating on the movement is typical for these early Lemania movements in Omega watches and later models have guilt colored movements. The dial is slightly tarnished but only visible by close inspection. The stainless steel case and back are in great condition with a few marks from curious admirers and watchmakers. I do not have a service history but there is oil in all the right places and I will recommend a service in two to three years. Asking USD 4000 plus shipping. I ship worldwide. I have the same nickname on several forums and I am on the good guy's list here and there.
