Abstract

A watchcase and watchframe suitable for mating and unmating one with the other by the use of a sealing means suitable for slidably translating the case within the frame and providing a substantially contiguous fit of the case within the frame.

Claims

1. A watchcase and a watchframe suitable for mating and unmating one with the other comprising:

(a) A watchcase having a mating surface which surface has a recessed groove therein, a shoulder, a top surface and a back surface;

(b) A watchframe having a mating surface, an interior rim, a normal exterior surface, an exterior rim, a top opening, and a bottom opening;

(c) A mating means substantially fixed within said recessed groove of the mating surface of the watchcase which means is suitable for mating the watchcase with the watchframe by slidably translating the mating surface of the watchcase within the mating surface of the watchframe to provide a substantially contiguous fit between the mating surfaces of said watchcase and watchframe;

(d) Said watchcase and watchframe mating by maintaining the watchframe stationary relative to the watchcase, placing the top surface of the watchcase into the bottom opening of the watchframe, applying sufficient pressure to the back surface of the watchframe, slidably translating the watchcase into the watchframe, substantially abutting said watchcase shoulder with said interior rim of the watchframe, said mating means substantially abutting both the mating surface of the watchframe forming a substantially contiguous fit between both mating surfaces;

AND

(e) Said watchcase and watchframe unmating by maintaining the watchframe stationary, applying sufficient pressure to the top surface of the watchcase, slidably translating the watchcase out of the watchframe.

2. A watchcase and watchframe as in claim 1 wherein said watchcase is further comprised of a wind and stem, said watchframe having a slot between its mating surface and its normal exterior surface, such that upon slidably translating the watchcase into the watchframe the stem moves within the slot.

3. A watchcase and watchframe as in claim 1 wherein said mating means is an annular ring comprised of natural rubber, synthetic rubber or plastic.
