I'm really looking to add these watches to my collection. If you have a 5960P, I'd prefer it to be complete. I had one, sold it, and now miss it terribly As for the 3448, and 570, they do not have to be complete, but should be in working order. I have solid references I can provide and am interested in a cash deal.
If you have any interest in a screwback PP sweep seconds, I have an amazing Ref. 2508 for sale with an incredible bronze patina original luminous dial and hands. The watch is nearly perfect, with PP strap and buckle. Just overhauled and running perfectly. I'm asking $20K plus shipping.
