The Certina 28-151 watch movement, produced from 1940 to 1951 with approximately 130,000 units made, was designed for high-grade small-scale production. This version of the 982 movement features a manual wind mechanism, sub second function, Breguet hairspring, and an escapement wheel cap in a gold setting. It remains one of the best iterations of the 982 movement series. The overall production volume of the 980/982 family, including all models, reached around 1,400,000 pieces during the period spanning 1934 to 1954.
