STRENGTH

Twenty-five years ago in acquainting jewelers  with the strength of the Jas. Boss Stiffened Gold Watch Cases, an enterprising salesman used the method here shown.

Jas. Boss Cases are still the strongest cases made. As good as solid gold in appearance. Better than gold in wearing quality. Less than solid gold in cost. In a

JAS.BOSS STIFFENED GOLD WATCH CASE

there is a layer of very hard composition between an inside and outside layer of solid gold reducing the cost of the case, and adding greatly to its strength.

BOSS Cases are guaranteed to wear for 25 years; are recognized as the standard, and sold as such by all jewelers. Write us for a booklet.

The Keystone Watch Case Company, Philadelphia.
