Vintage Must De Cartier Paris 925 Quartz Argent Plaque or G20M Swiss Wrist Watch. I'm not a watch expert so bear with me, I'll do my best. This was from a large lot of watches of a retired watch maker. I know it has been sitting for years, so you should probably take it in for fresh battery, oiling/service, whatever they do on these old watches. The band is cracking and needs to be replaced. The watch looks very nice to the naked eye, besides being dirty and tarnished. When I look with a lupe, the crystal and housing/back has some light scratches/wear. The back is stamped Cartier Paris 925 Quartz Argent Plaque or G20M Swiss Swiss 17 056503. Uncleaned, as found. It is as you see in the pictures. Please look close at pictures, what you see is what you will receive, no more, no less. No returns.
