18ct yellow gold Piaget ref. 1401/1 BETA 21 wristwatch with lapis lazuli dial. Made 1970

The BETA 21 was created in 1969 and it was agreed by the 20 Swiss houses to produce 6,000 of these movements. Later that year, a few hundred of the BETA 21 watches were released at Basel, setting a new record at the Fair. The BETA 21 movement was accurate to 5 seconds per month, which was far superior to any automatic and manual-winding watch at the time. The design for the BETA 21 watches were also very characteristic of the era --they were generally thick, angular, and even chunky (partly out of necessity as the first generation of quartz movements were comparatively large.)
