  • the watch comprises a case 1 and a face 2 provided with a 12-hour time dial 2a and a spiral thermometer 2b with a temperature range from -10 to 50.
  • a midget lamp 3 which projects sufficiently from the face to provide the best possible illumination of the dial 2a and the needles 4, 5 and 5a of the time piece, and also the thermometer.
  • the knob 6 for winding the watch movement is provided at one side of the case in the usual manner.
  • a push button 7 on the side of the case 1, preferably near the knob 6, makes it possible to close the electric circuit of the lamp 3 by depressing the button in the direction of the arrow 8 when it is desired to illuminate the face.
  • the push button is returned to its original position by a spring (not shown).
  • FIG. 2 there is fitted into the case a body or support part 10, of unbreakable, injection mouldable insulating plastics material of any suitable type, which is housed in the case 1 and is shaped to match entirely or partly the shape of the case.
  • a body or support part 10 of unbreakable, injection mouldable insulating plastics material of any suitable type which is housed in the case 1 and is shaped to match entirely or partly the shape of the case.
  • This figure shows the portion of the case 1 from which the winding knob 6 and push button 7 project.
  • Part 10 In the support part 10, which must constitute a means of projection against shock in at least two directions, recesses are provided to receive a watch movement 9 and an electric battery 11.
  • Part 10 has fastening points 10a and 10b for elastic metal blades 12 and 13 intended to make electrical connections between the battery 11 and a lead wire 15 of the lamp 3 on the one hand, by means of the blade 12, and on the other hand between the other lead wire 14 of the lamp and the contact point of the push button 7 by means of the blade 13.
  • contact is controlled by applying pressure to the winding knob 6 in the direction of the arrow 16, thereby displacing the watch movement in the same direction; such displacement, amounting to only a few tenths of a millimetre, which is imperceptible from the outside, is sufficient to operate a switch reliably.
  • a support part 21 of plastics material is housed in the case 1.
  • the support part 21 two recesses are provided, one of which houses the watch movement 9 and the other the battery 11.
  • the recess for the movement 9 is obviously designed to allow the latter to move in the direction of the arrow 16 (FIG. 3) when pressure is applied in that direction to the knob 6.
  • an elastic arm 18 which has at least three functions, namely to carry the lamp 3, the application of pressure to return the watch movement 9 in the opposite direction to the arrow 16, and thirdly, the carrying of a contact sleeve 19 to which one of the wires 20 of the lamp 3 is directly connected.
  • coil springs 22 and 23 which are held in compression by the removable metal base plate 26 closing the back of the case 1, and by means of which the assembly is fixed inside the case 1.
  • the wire 24 of the lamp 3 is connected to earth by engaging this wire between two turns of the spring as indicated at 23a.

  • the battery 11 is pressed against the back cover plate 26 by a pad 25 of elastic material in the bottom of the battery recess in the body part 21 which bears against the watch face.
  • the lamp circuit can be completed at the point 19a on the sleeve 19, when the latter is brought directly into contact with the body of the battery 11, by application of the knob 6 in the direction of the arrow 16, which is possible because of the elasticity of the arm 18, thereby illuminating the lamp.
  • the external shape of the watch movement 9 is independent of the invention, that is to say circular or rectangular movements, for example, may be used provided the recess in the body part 10 or 21 has the required shape and dimensions.
  • the modified electric circuit shown in FIG. is applicable to the embodiment illustrated in FIGS. 3 and 4.
  • a lead wire 31 to the lamp 3 is connected to the sleeve 19 and the other lead wire 30 is connected to a contact 29 in the bottom of the battery recess in body part 21.
  • This contact 29 makes contact with the central pole 11a of the battery 11, which is firmly held against it by the bottom 26, but with the interposition of a disc 32 of insulating elastic material.
  • the circuit is made by direct contact between the point 19a of the sleeve 19 and the body of the battery 11 when pressure is applied to the knob 6 in the direction of arrow 16.
  • the sleeve 19 has a suificiently wide slot to be turned by means of a suitable tool in order to change the distance separating the contact point 19a from the battery. This feature is useful for making the final adjustment, taking into account variations in manufacture.
  • the simple sleeve 19 may moreover be replaced by a rotating contact having an eccentric portion permitting the same adjustment.
  • the sleeve 19 may be dispensed with.
  • the wire 31 is wound several times around the stud and secured in a slot.
  • the contact 29 (FIG. 5) may be eliminated.
  • the watch case 1 contains a spiral thermometer, the dial 2b of which has two graduations, one corresponding to the actual temperature on the users arm, and the other to the approximate ambient temperature.
  • thermometer e.g. a barometer, hygrometer, a timer, a second watch movement intended to show the time in other time zones, and so on.
  • These alternative devices may be situated in the same position and of a size so as to reserve, preferably in the centre, a space to receive at least one miniature electric lamp intended to illuminate the dial and the hands.
  • the watch movements having two or three bands must obviously be of relatively small dimension, corresponding for example to the size of a movement for a ladys wristwatch.
  • the glass of the case may be provided with reflecting surfaces in order to direct light towards points to be illuminated.
  • the recess in the body part in which the watch movement is housed may be provided with grooves within which the movement is slidably mounted in order to permit displacement of the latter on depression of the knob 6.
