Up for sale is a vintage GRANDE PRIX LONGINES 4878857. I don't see a jewel count so I hope the number helps you get the jewel count and date it. The dial has a couple problems. Check out the pictures, it has a problem at around the 12 O'clock and a couple tiny marks between the 4 and 5 O'clock and it has has a couple problems in the crystal at that time. I set it and wound it and it is running fine. I don't know when it was last cleaned and serviced so that should be done when it's received to keep it running.  Please check all the pictures and bid for what you know about vintage pocket watches. I am selling it AS IS.  If you have any questions please email and I'll try to help.   *** BUYER TO PAY $8.50 SHIPPING IN THE U.S.  *****
