Aircraft clock with stopwatch ASF-1
Next 6 photos.
Duration of one complete winding springs at least 3 days. The diurnal variation of temperature (20 ± 5) ° C ± 20 seconds. Start of work hours - after two complete revolutions of the crown. Number of jewels 25.
Lower connection terminals for catering 27 volts. Used as a heater for thermal stabilization.
Watch issued before 70 coated hands and dial 226. radiya- with the addition of salts of radium-226 is part of the continuous phosphor (SPD). In the body, it behaves like calcium - about 80% In the body radium accumulates in bone. High concentrations of radium cause osteoporosis, spontaneous fractures and malignant bone tumors and hematopoietic tissue. The danger is also radon - a radioactive gas decay product of radium.
Ambient temperature -60 ... + 60 ° C Dimensions 85h91, 4h91, 4 mm. Weight 0, 655 kg.
More such modifications airborne hours.
Mechanisms hours.
