Since Lincoln's Time,

more than 7,000,000 Jas. Boss Stiffened Gold Watch Cases have been sold. Many of the first ones are still giving satisfactory service, proving that the Jas. Boss Case will outwear the guarantee of 25 years. These cases are recognized as the standard by all jewelers, because they know from personal observation that they will perform as guaranteed and are the most serviceable of all watch cases.

Jas. Boss Stiffened Gold Watch Cases

are made of two layers of solid gold with a layer of stiffening metal between all welded together into one solid sheet. The gold permits of beautiful ornamentation. The stiffening metal gives strength. United they form the best watch case it is possible to make. Insist on having a Jas. Boss Case. You will know it by this trademark.
