Abstract

A waterproof watch having a case and a base which are sealed in a water tight manner without the use of screw threads, is provided. The watch base is composed of a memory form alloy which may or may not be reversible. The watch base is deformed while in its Martensitic state and loosely fit adjacent a sealing portion of the case. The base is then permitted to rise above the Martensit/Austenit conversion temperature into its Austenitic state so that it returns to its undeformed shape and engages the sealing portion of the case in a water tight pressure fitting manner. The conversion temperature should be -20 DEG C. or below. A tubular conduit for the winding stem may also be composed of memory form alloy for sealing engagement with the case.
