Yeah, I bought it on a whim only to discover upon opening it was a Roamer circa 1948, needed a lens polish and a new 3rd wheel, some keen watchmaker had done a repair in the past to the 3rd wheel which had a broken pinion by welding a new one on but he didn't get it precisely centralised making running performance intermittent.
I am not sure if it started life as a sterile dial which is possible at that time or whether some enthusiastic watchmaker just wanted to clean it up however it certainly has nice dial furniture and is very photogenic and a jumbo of it's day.
