Dueber Watch Case Manufacturing Company
The Dueber Watch
Case 
Manufacturing Company's
Establishment is situated in the building on the south-west corner of Fourth
and Race Streets.
Mr. John C. Dueber established this business in 1864. The business grew steadily ever since, and the Dueber Watch Case Manufacturing Company was incorporated in 1873. The floor-space now occupied by their manufactory exceeds 12,000 square feet.
The accompanying engraving illustrates one of the main rooms of their manufactory, where about 60 skilled workmen are employed. They manufacture all kinds of Gold and Silver Watch Cases, and the reputation the "Dueber" Watch Cases have made for themselves, in all the States, from Maine to California, is abundant proof of their superiority and intrinsic value.
Long years of experience enables the Dueber Watch Manufacturing Company to turn out watch-cases of great beauty, and in those of high cost great elaboration of detail. It has always been supposed owing to the want of experience, great skill required, and the high price of labor in America that the business of watch-case making, and particularly the finer descriptions of these articles, would be confined almost exclusively to Switzerland, but the American energy and enterprise have supplied ingenious machines and expert workmen, whose efforts have been crowned with success, and many of the beautiful cases made by this company vie in costliness, workman-ship, and finish with the finest productions of the best foreign artists.
