ABSTRACT:
A vise is provided to assist in performing various watch repair and maintenance functions and includes a pair of jaws having generally planar and parallel opposing surfaces. The jaws are supported for guided relative movement toward and away from each other along a path disposed substantially normal to the opposing surfaces thereof. The jaws include cylindrical recesses opening outwardly of the opposing surfaces and disposed substantially normal thereto. The opposing jaw surfaces have thin panel members secured thereover constructed of shape retentive, stiff but slightly deformably resilient material and the panel members include circular openings therein substantially coaxial with and of the same diameter as the recesses. A thin circular watch case may be clamped between the jaws with four spaced surface areas of diametrically opposite portions of the watch case engaged by correspondingly spaced portions of marginal portions of the stiff panel members defining the aforementioned circular openings.
