The wristwatch with radio was developed in 1986 by the Riga PO &quot;Radiotekhnika&quot;. A complex creative youth team under the leadership of S.A. Zhuravlev at the Microelectronics Design Bureau on the topic &quot;Hybrid-6&quot; has developed 3 versions of clocks with a radio receiver and made prototypes. In the first version of 1986, the watch was electronic, in the second version of 1987 - an electromechanical quartz watch based on the 2356 mechanism of the 2nd Moscow ChZ, the third version provided for the placement of a radio receiver in a keychain or pendant. The estimated cost of the 1st microassembly RPd Ch-3 for watches in serial production (20,000 pieces per year) was 3 rubles. 50 kopecks

A miniature direct-amplified radio receiver is made in a light, plastic case of an electronic (electromechanical) wrist watch or in the form of a pendant. With the help of a built-in magnetic antenna, any local broadcasting station is received in the medium-wave range. The sound volume is adjustable. The power supply of the clock mechanism and the receiver is carried out separately, from one element of the SC-32 type for each device. The aesthetically subtle decorative color finish and good legibility of the graphic signs make the clock radio modern and the pendant receiver a fashionable element of decoration. Technical characteristics: The range of received frequencies of MW - 525 ... 1605 kHz. Load resistance - 80 ohms. Consumption current - 4 mA Supply voltage: nominal 1.5 V, minimum 1.1 V. Dimensions of the radio clock - 44x37x12 mm. Weight - 15 gr.
