Record summary
Held and catalogued by Swedish National Museum of Science and Technology (object number S_TEK_object_TEKS0007183), this is a clock by Radionics, dated 1900–1999. The Atlas places it in the Modern Mechanical Horology period (1945 – 1969) of its Clocks collection. The record is illustrated with 1 photograph.
Assembled from the source record's structured fields. Dates and attributions are given as the source states them; where a field is missing the Atlas leaves it blank rather than estimating.
Catalogue description
Catalogue description from Swedish National Museum of Science and Technology (Swedish)
Armbandsur i etui, originalförpackning. Black Watch är tillverkad i svart plast, med en femsiffrig LED-display. För att spara ström lyser displayen endast upp när man trycker på panelen under displayen, då visas antingen timmar och minuter eller minuter och sekunder med röda siffror. En exklusivare variant av uret kunde även visa datum. Batterierna räckte tio dagar, men var inte lätta att byta. Plasthöljet var fäst med snäppen, som tyvärr gick sönder efter en tids användning. Kvartskristallen som genererade tiden var temperaturkänslig och klockan gick därför olika fort vinter och sommar.

Historical context
Modern Mechanical Horology (1945 – 1969)
Tool watches for divers, pilots and astronauts; electric watches anticipate the electronic age.
Post-war clocks combined new materials and industrial design: plastic and metal cases, battery-powered transistor movements from the late 1950s, and design classics by George Nelson, Max Bill and others. The first caesium atomic clock (1955) moved the definition of time from astronomy to physics.

Atlas type guide
Quartz, digital and designer clocks
Transistors, integrated circuits and quartz crystals brought precise timekeeping into every household after the 1960s. Quartz clocks divide the 32,768 Hz vibration of a tuning-fork crystal down to one pulse per second to drive a stepping motor or a digital display. Digital clocks with flip cards, nixie tubes, LEDs and LCDs, and clock radios became emblems of modern design.
Designers such as George Nelson, Max Bill, Dieter Rams and Richard Sapper treated the clock as a field for industrial design; manufacturers including Junghans, Kienzle, Braun, Seiko, Citizen and Sony produced landmark models now collected and held by design museums.
What to look for
- Battery compartments and quartz movement labels.
- Display technology: split-flap cards, LED, LCD, vacuum fluorescent.
- Designer names and model numbers on the base or back.
Dating clues
- Transistorised clocks: from the late 1950s.
- Consumer quartz clocks: from the early 1970s.
- Radio-controlled clocks: from the mid-1980s.
