Abstract
Abstract A waterproof sport watch utilizing a solid state digital watch module which is completely enclosed in a sealed casing, with no protruding buttons or other actuating devices. The module is fixed in a casing having a removable back, sealed by an O-ring, for battery and servicing access. The front of the watch is enclosed by a transparent cover, also sealed by an O-ring, the cover being rotatable to indexed positions and having integral cams which actuate the watch module controls, a stopwatch action being obtained by squeezing the cover at one indexed position. The watch is particularly suitable for use by divers and is very easy to operate under water.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
118 words
A waterproof watch, comprising: a case; a solid state digital watch module fixed in said case, the module having a plurality of spaced, function initiating contacts thereon, and a data display panel on a front surface thereof; a front cover rotatably mounted on and sealed to said case, at least a portion of said cover being transparent and revealing said display panel; said module having contact engaging electrical switch means thereon at the position of each contact on said module; said cover having actuating means for actuating said switch means selectively at specific rotational positions of the cover; and said case having indexing means therein engaging said cover to index the cover to the specific switch actuating positions.
Claim 2
Dependent Claim
118 words
A waterproof watch, comprising: a case; a solid state digital watch module fixed in said case, the module having a plurality of spaced, function initiating contacts thereon, and a data display panel on a front surface thereof; a front cover rotatably mounted on and sealed to said case, at least a portion of said cover being transparent and revealing said display panel; said module having contact engaging electrical switch means thereon at the position of each contact on said module; said cover having actuating means for actuating said switch means selectively at specific rotational positions of the cover; and said case having indexing means therein engaging said cover to index the cover to the specific switch actuating positions.
Claim 3
Dependent Claim
49 words
A waterproof watch according to claim 1, wherein said switch means includes a resilient conductive finger element spaced from and biased away from each of said contacts; said actuating means including at least one cam for actuating each finger element individually and closing the circuit with the respective contact.
Claim 4
Dependent Claim
62 words
A waterproof watch according to claim 2, wherein said case has a socket therein at each contact position, the socket having a downwardly and inwardly inclined ramp, and an actuating element supported on the ramp and engaging the finger element; said cam being shaped to depress the actuating element against the ramp and thereby deflect the finger element to engage the contact.
Claim 5
Dependent Claim
26 words
A waterproof watch according to claim 2, and including a common conductive ground plane attached to said module, said finger elements extending from said ground plane.
Claim 6
Dependent Claim
35 words
A waterproof watch according to claim 2, wherein said cover and said case have a resilient sealing O-ring therebetween, said cover having an inner surface spaced from said case for limited depression of the cover.
Claim 7
Dependent Claim
59 words
A waterproof watch according to claim 5, and including an actuating element bearing against each of said finger elements, said cam having a face portion for engagement with a selected one of said actuating elements to move the associated finger element partially toward the adjacent contact and to complete movement of the finger element when said cover is depressed.
Claim 8
Dependent Claim
56 words
A waterproof watch according to claim 1, wherein said indexing means includes a plurality of circumferentially spaced sockets in said cover, and a detent in said case biased to seat in said sockets; a shallow channel interconnecting said sockets, said detent having a range of deflection sufficient only to ride in said channel between the sockets.
Claim 9
Dependent Claim
18 words
A waterproof watch according to claim 7, wherein the trnsparent portion of said cover reveals said indexing means.
Claim 10
Dependent Claim
71 words
A waterproof watch according to claim 3, wherein said cover has limited freedom of axial movement on said case; said cam having a face portion for engagement with a specific one of said actuating elements at a particular indexed position of the cover, to depress that actuating element partially and deflect the associated finger element partially toward the contact, the switch closing action being completed by axial depression of the cover.
Claim 11
Dependent Claim
19 words
A waterproof watch according to claim 1, and including a back plate removably mounted and sealed in said case.
