Definitions

the invention relates to an electromechanical wristwatch.
the invention is intended to create a completely self-sufficient wristwatch that is therefore absolutely problem-free for the user.
a completely hermetically encapsulated wristwatch with a time-keeping electromotive pointer mechanism is also equipped with a radio clock receiving device including radio clock control device and with a long-wave antenna for occasional reception of coded absolute time information ; the entire clock including these radio clock devices being operated from an electrical memory which is recharged through at least one solar cell extending approximately in the dial plane when the light falls through the watch glass.
the clock thus starts up automatically in a bright environment and then automatically sets its hands to the currently applicable time, taking fully automatic account of the summer-winter time changes.
the watch case is provided at such a location (preferably in the case bottom) with a hermetically closable opening through which a contact point is accessible for a test probe, which is in electrical connection with one of the storage poles directly or via the energy control circuit.
the correct storage function can be checked by observing the potential increase in the storage due to the sudden increase in solar cell radiation (for example with a very bright lamp). Ggffs.
a direct electrical rapid charge of the storage device can also take place via such a contact point, for example after prolonged storage in a dark environment immediately before delivery a customer.
this through opening into the interior of the housing can also serve to build up a positive pressure in the housing in a manner known as such for axially pressing out the watch glass and thus to release the underlying arrangement of the solar cell and circuit board with clockwork above the memory for dismantling.
the wristwatch 11 shown has an essentially flat-pot-shaped housing 12 made of metal, ceramic or plastic with an integrated base 13.
the inside accommodates, approximately centrally, in a recess 14 a contact spring 15 which bulges out of it slightly, against which an electrophysical (capacitor) or electrochemical (accumulator), approximately flat-cylindrical memory 16 is pressed axially.
a printed circuit board 18 is axially pressed onto a radial projection 19 on the inner surface 20 of the essentially hollow cylindrical housing wall 21.
the axial intermediate space between the opposite pole 22 of the memory 16 and the lower surface 23 of the printed circuit board 18 facing the bottom 13 is bridged in a contact-making manner by a spiral spring 24 fastened beneath it.
Radio clock receiving device 26 including radio clock control device 27 with time-keeping oscillating circuit 28 and optionally display driver circuit 29, all of which are arranged in the vicinity of the centrally positioned pointer and wheel mechanism 30, on the one hand via through-contact to the spiral spring 24 and on the other hand via the contact spring 15 and supplies an internal metallization or the metal body of the housing 12 itself with electrical operating energy.
the supply of the radio clock receiving device 26 serves the contacting of a laterally attached to the circuit board 18 terminal spring 31 to an insulated in the housing 12 built-in coupling sleeve 32 for the pin 33 at the end of an antenna line 34, which for the (not shown on the drawing) antenna coil one magnetic long-wave antenna 35 in the bracelet 36 of the wrist watch 11 connected to the housing 12.
the end of the antenna line 34, the connector pin 33 adjoining here and the coupling sleeve 32 fixed to the housing engage approximately coaxially and transversely to the movement axis 37, that is to say in the extension of the connecting direction of the bracelet 36, into a lateral region of the housing wall 21; and against the free end of the coupling sleeve 32 projecting through the wall 21, the connection spring 31 for the signal connection from the antenna 35 to the radio clock receiving device 26 is non-positively in the housing interior 17.
an arrangement of at least one solar cell 38 extends through the interior 17 of the housing 12 and is at the same time configured as a watch dial. It rests directly or indirectly (then with the interposition of flat supports) on one side of the Wall 21 protrudes radially into the housing interior 17 shoulder 39 and also on an elastic bridging contact 40.
This is preferably a conductive rubber block or a cylindrical spring for deriving the current supplied by the solar cell 38 from the housing 12 via the printed circuit board 18 and the spiral spring 24 to the opposite pole 22 of the memory 16.
the solar cell 38 has a through opening 42 concentric with the housing axis 37 for the shafts 43 of the pointers 44 driven from the factory 30.
the current time display position of the hands 44 is detected directly or indirectly via a position detector 45 installed in the work 30, preferably in the form of a gear train light barrier, and is sent to the radio clocks for checking and, if necessary, radio-controlled correction via the circuit on the circuit board 18. Control device 27 transmitted.
a window 46 for the presentation of an electro-optical cell 47 preferably a liquid crystal display, arranged underneath, which window is removed from the circuit board surface 25 by means of an elastic multiple contact 48 (for example a so-called zebra conductive rubber) is pressed against the back of the solar cell 38.
an elastic multiple contact 48 for example a so-called zebra conductive rubber
the axial pressure of the solar cell 38 in the direction against the housing bottom 13 and thus against the contacts 40, 48 and the bearing on the wall shoulder 39 is carried out by means of a support ring 49 inserted in the wall inner circumferential surface 20 from the watch glass 50, the under radial intermediate layer of a sealing ring 51 is axially pressed into a circumferential recess 52 in the plane of the opening of the pot-shaped housing 12 and thus not only the stack axially fixed from memory 16, printed circuit board 18 and solar cell 38, but also hermetically seals the housing interior 17.
a thickened side region 53 at the transition from the floor 13 to the circumferential wall 21 of the housing 12 is traversed by a threaded bore 54 into which the shaft of a small machine screw 55 can be screwed in order to hermetically seal the interior 17 of the housing.
the radially protruding head 56 is embedded in a recess 57 coaxially surrounding the threaded bore 54 on the outside of the housing base 13 and pressed against a sealing ring 58 inserted therein.
the connecting hose (not shown) of a pump can be connected to the threaded bore 54 in order to generate excess pressure in the interior 17 of the housing under the watch glass 50 and thereby axially upward from its wall surround with the sealing ring 51 ( So from the floor 13) to push out if the wristwatch 11 is to be dismantled, for example, for service purposes.
the stylus of a measuring instrument can be inserted through the temporarily cleared threaded bore 54 in order to reach a contact point 59 formed on the bottom surface 23 of the printed circuit board 18 facing the bottom 13, via which (opposite the housing 12 as the opposite pole) an electrical potential can be tapped.
This potential can be a circuit point in the course of radio clock signal processing and electrical clockwork control on the printed circuit board 18, but preferably the charge potential of the memory 16 immediately or in front of the energy control circuit 41.
the function of the memory 16 or its energy control circuit 41 can be checked via the circuit contact point 59 to determine whether a The voltage rises as a function of a strong increase in the light irradiation through the watch glass 50 onto the solar cell 38 and the memory 16 is thus still ready for operation.
an electrical charging device for an immediate express charge of the memory 16 can also take place via this, for example after completion of the production in the factory or by the watchmaker immediately before the wristwatch 11 is handed over to a customer.
