··LemaniacDon't treat it as fact yet, It was merely a comment someone from the Omega archive made last year at the Speedy Tuesday event. He said that in the past what happened was the client that requested an extract supplied information about the watch, and that supplied information would go on the extract which was a less than ideal situation, as while Omega was meticulous in record keeping, the Lemania produced Speedmasters were one of the black holes in those records that was never filled. I don't know ultimately what came of it and have not tested that.
It depends on how early I guess? No issues getting an extract on my 105.003 last fall.
As no chronograph movement was made in house by Omega between the early 30's and up to modern times I am surprised why just these from the 50's should give them problems?
