About 1880 a few Swiss immigrants set up in N.Y. city to make the best pocket watch cases.
Jeannot & Shiebler did the best quality gold cases for the finest Swiss, German and Americam movements and dealers like Tiffany. Little used example here is 1884 Waltham 8 size. Has handcrafted floral arrangement not the usual prepared stick-on pieces. Has their hard gold alloy bow liner to minimize chain hook wear. Learned today after 40 years of buying and selling J&S was first with these.
