Pocket watch enthusiasts might like to see this pair of Key wind Jones. The one on the left is a pattern S in a silver lepine case, the one on the right is a patten R in an 18K gold savonnette case. Interestingly they are both 15 jewel and the only difference appears to be the balance. The S has a flat balance and the R a Breguet balance. As with the crown wind versions, the S is inscribed "Intnl Watch Co New York" and the R is inscribed "International Co New York".
