Abstract
Abstract An analog watch for training children to read the current time having a flashlight installed in the watch case. The flashlight power supply is connected to the light emitting flashlight bulb through an electrical circuit which automatically turns the flashlight off after an adjustable time delay to preserve battery power. The watch time indicating face has numbers and dots to represent hours, and numbers and dots that represent minutes. These may be of different colors and may be adapted to glow in the dark after activation by light from the flashlight or from a face illuminating light source. The watch face has dots at half-hour intervals to indicate that the current time is at the half hour. All hour numbers and time-indicative dots may be embossed on the crystal face of the watch so that the minute hand does not pass over and obscure these symbols.

Claim 1
Independent Claim
69 words
A time keeping and displaying wrist mountable watch having a flashlight mounted in the case thereof, said flashlight comprising a power supply for supplying electrical power to said flashlight, said power supply electrically connected to at least one light source, and time delay means for automatically extinguishing said light source after a time delay following the energization of said light source by the electrical deenergization of said light source.
Claim 2
Dependent Claim
69 words
A time keeping and displaying wrist mountable watch having a flashlight mounted in the case thereof, said flashlight comprising a power supply for supplying electrical power to said flashlight, said power supply electrically connected to at least one light source, and time delay means for automatically extinguishing said light source after a time delay following the energization of said light source by the electrical deenergization of said light source.
Claim 3
Dependent Claim
26 words
The watch of claim 1 having an electrical switch which controls the flashlight, serving as an on-off switch, wherein said on-off switch is itself continuously lit.
Claim 4
Dependent Claim
31 words
The watch of claim 1 having an electrical switch which controls the flashlight, serving as an on-off switch, wherein said on-off switch is itself continuously lit by a light emitting diode.
Claim 5
Dependent Claim
21 words
The watch of claim 1 having symbols indicative of the time of day embossed on the crystal face of the watch.
Claim 6
Dependent Claim
136 words
A time keeping and displaying wrist mountable analog watch having a flashlight mounted in the case thereof, said flashlight comprising a power supply for supplying electrical power to said flashlight, said power supply electrically connected to at least one light source, and time delay means for automatically extinguishing said light source after a time delay following the energization of said light source by the electrical deenergization of said light source, and said analog watch having minute numbers and minutes dots positioned to represent minutes on the face of said watch which minute numbers and minute dots are of a first color, and having thereon said watch face hour numbers and hour dots positioned to represent hours of time wherein said hour numbers and hour dots are of a second color not identical to said first color.
Claim 7
Dependent Claim
136 words
A time keeping and displaying wrist mountable analog watch having a flashlight mounted in the case thereof, said flashlight comprising a power supply for supplying electrical power to said flashlight, said power supply electrically connected to at least one light source, and time delay means for automatically extinguishing said light source after a time delay following the energization of said light source by the electrical deenergization of said light source, and said analog watch having minute numbers and minutes dots positioned to represent minutes on the face of said watch which minute numbers and minute dots are of a first color, and having thereon said watch face hour numbers and hour dots positioned to represent hours of time wherein said hour numbers and hour dots are of a second color not identical to said first color.
Claim 8
Dependent Claim
73 words
The watch of claim 5 wherein said analog watch has a minute hand 12 the position of which is proportional to the present minute of the current time of day, said minute hand 12 being dimensionally approximately a rectangle having a thin thickness T which is substantially smaller than the width W of the hour numbers 15 such that minute hand 12 cannot obscure numbers 15 by passage over said hour numbers 15.
Claim 9
Dependent Claim
37 words
The watch of claim 5 wherein said watch further comprises a plurality of half-hour dots, being small circular dots positioned along the perimeter of a circle at positions proportional to the intervals of half-hours of current time.
Claim 10
Dependent Claim
21 words
The watch of claim 5 having symbols indicative of the time of day embossed on the crystal face of the watch.
