I am very proud to offer for the first time a vintage Vacheron Constantin watch on Time Merchants. It is very special and specific watch, featuring a 36mm case with a rare two tone dial for the 4870 model. I suspect the crown to be a replacement although most are not signed on this reference. The watch has just been serviced and works very well.
