Record summary

Held and catalogued by Science Museum Group, London (object number 1990-746), this is a stop-watch, made in United Kingdom, dated 1971. The Atlas places it in the Quartz Revolution period (1969 – 1990) of its Instruments collection. Recorded dimensions: overall: 20 mm x 140 mm x 120 mm, 0.08kg. 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

Historical context

Quartz Revolution (1969 – 1990)

Seiko's Astron begins mass quartz timekeeping; traditional industries contract sharply.

Electronic timing replaced mechanical instruments in sport, industry and navigation.

Timers, stopwatches, chronoscopes and time recorders

Instruments for measuring short intervals or recording when something happened form a large and practical branch of horology. Sports stopwatches and split-seconds timers, laboratory chronoscopes (such as Hipp's, which measured thousandths of a second for psychology and ballistics experiments), metronomes for music, watchmen's clocks that recorded patrol rounds, and the time recorders that clocked factory workers in and out all derive from clock and watch technology.

These objects matter historically because they show timekeeping leaving the observatory and the drawing room and entering industry, science and sport. Many were mass-produced, and their dials, scales and patents chart the rise of electrification and industrial management.

What to look for

  • Scales graduated in fifths, tenths or hundredths of a second, or decimal minutes for industrial use.
  • Start, stop and reset push-pieces; a second hand that can be stopped independently (split seconds).
  • Recording devices: paper discs or tapes, printing mechanisms, keys or punches.
  • Patent numbers and dates on the dial or case, which give a terminus post quem.

Dating clues

  • Hipp chronoscopes were made from the 1840s into the twentieth century.
  • Employee time recorders spread from the 1890s (Bundy, IBM, International Time Recording Co.).
  • Quartz and electronic timers replaced mechanical stopwatches in sport from the 1970s.
