Catalogue description

Lot description — Sphere Auctions LLC

This is a Bulova Accutron wristwatch, powered by Bulova's tuning fork electronic movement — one of the first battery-powered watch technologies, introduced in 1960. Case back date code "M5" dates this piece to 1965.Dial is signed "ACCUTRON" with the tuning fork logo at 12 o'clock, applied stick hour markers, a printed dot minute/railroad track, and a thin sweep second hand. The dial shows significant age discoloration and spotting.Case back is stamped "BULOVA," "WATERPROOF," "PATENTED," "STAINLESS STEEL," with case reference C10363 and date code M5.Bracelet is a stainless steel expansion band with a woven/basketweave textured finish, stamped "TWISTON U.S.A."Not tested for working condition — as an electronic tuning-fork movement, it will need a compatible battery and likely servicing to confirm function; these movements can be costly to restore if the drive coil has failed.

Historical context

Modern Mechanical Horology (1945 – 1969)

Tool watches for divers, pilots and astronauts; electric watches anticipate the electronic age.

The classic era of the mechanical wristwatch: dive watches, chronographs for motor racing and space flight, GMT watches for jet travel, slim dress watches, automatic calendars, and the rise of Japanese manufacturers alongside Swiss, American, German and Soviet industries.

Atlas type guide

Quartz, digital and electronic watches

Electronic watches arrived in three steps. The Hamilton Electric 500 (1957) was the first battery-powered wristwatch, still with a balance; Bulova's Accutron (1960) used a tuning fork. On 25 December 1969 Seiko released the Astron 35SQ, the first quartz wristwatch, closely followed by the Swiss Beta 21 group. In 1972 Hamilton's Pulsar introduced the LED digital watch, and LCD displays soon made digital watches cheap.

The 'Quartz Crisis' that followed devastated the Swiss mechanical industry, which lost two-thirds of its workforce between 1970 and 1984 before recovering with the Swatch (1983) and the luxury mechanical revival. Solar, radio-controlled, kinetic and connected smartwatches continue the electronic line.

What to look for

  • Battery hatch in the case back and calibre markings with 'Quartz' or a crystal frequency.
  • Display technology: LED (red, push-button) versus LCD (always-on).
  • Tuning-fork hum and a smoothly sweeping seconds hand on Accutrons.
  • Model and reference numbers, often printed on the back.

Dating clues

  • Electric balance watches: from 1957.
  • Tuning-fork watches: 1960–c. 1977.
  • Quartz analogue: from December 1969; LED digital: 1972–c. 1978; LCD from 1973.
