To all whom it may concern:

Be it known that I, S. D. Engle, of Hazleton, Lnzerue county, and State of Pennsylvania, have invented a new and useful Improvement in Watches; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and' use the same, reference being had to the accompanying drawings, forming part of this specification.

The present invention mainly relates to the cases of that class of watches kuown as "hunting-watches," the object being to more perfectly exclude dust and dirt from the working parts or movement of the watch, it consisting in providing a separate and independent box or case from the ordinary watch-case for the movementof the watch, in which boxthe movement is secured in the usual manner now practiced for fastening it in the watch-case, the said movement-box being fastened in the watchcase in any proper manner to allow it to be easily and readily removed therefrom when so desired.
