This Swis-made watch was one of the first ever quartz wristwatches. The Japanese manufacturer Seiko was the first to release a quartz wristwatch on the market in 1969 (the 35-series 'Quartz Astron'), though the Swis industry had been developing their own quartz watches in parallel, resulting in the generic 'Beta 21' movement. 1970 saw several quartz watches exhibited at trade conferences including the Longines Ultraquartz and the Hamilton 'Pulsar', the first electronic digital wristwatch.
