HISTORY:
(1)- WADSWORTH WATCH CASE COMPANY: Born in Birmingham, England in 1845 and emigrating to America in 1857, Henry Wadsworth founded this company in 1889. H.A. Wadsworth & Co was located in Newport, Kentucky from 1889-1892 and then as the Wadsworth Watch case company of Newport until 1900 when they moved to Dayton, Kentucky until 1953. They earned a high reputation in the trade with their solid gold- and gold-filled cases. They sold cases to the Hamilton, Elgin and Waltham watch manufacturers. In 1953 they became a division of the Elgin National Watch Company of Illinois.
(2)- ILLINOIS WATCH COMPANY - The Illinois Watch Company (IWC) was formed by seven partners in 1869 under the name of the Illinois Springfield Watch Company. In 1879, a year they made their first nickel movement the name became the Springfield Illinois Watch Company. In 1882 they made their first mainspring in their own plant and the following year produced enamel dials for the first time. The final name change took place in 1885 when the name became the IWC. They used more names on their movements than any other company. The earliest watches bore the names of some of the original watchmaking partners on the movements and are the most valuable to collectors: e.g., Stuart, Mason, Bunn, Miller and Currier. The IWC was sold to the Hamilton Watch company in 1927. As the manufacture of watch movements developed both in quality and quantity, the American producer was quick to learn the lesson of their time, i.e., the necessity of specialization of watch movements for the use by railroad employees. The Illinois Watch Company was among the first to realize this lesson, and during the latter years of the 19th century, while not discontinuing its large output of moderate priced watches, nor abating constant effort to improve the quality of same, nevertheless sought the most highly skilled aid of workmen and inventors in producing a watch of the highest perfection. This means a watch to meet the exacting requirements of railroad service, and Illinois made a special effort in this direction by furnishing the "Sangamo" and the "Bunn", "Bunn Special", and "A. Lincoln" movements in 18 size, for the use of railroad men, so that those movements were well known wherever railroads were operated, and became the recognized standard watches for railway service.

PRICING:
This is well designed Art deco pocket watch and the back cover is most attractive. Judging by the comparables and the way that the pocket watch database priced the watch (which a=was in agreement with the comparables), I believe that if offered on the watch market today, it would have a fair market value in the range of $120-$140, with retail pricing about twice that amount.
