The Benrus CE3 watch movement is an open face calibre that features a stop- and addition function with pillar wheels. It offers two options for frequency: 36000 A/h and a doubled gear ratio from the seconds wheel to the escape wheel. This design ensures that the maximum displays and power reserve remain unaffected, allowing for identical dials in both frequency variants. The movement is likely manufactured by Valjoux, although it is often listed in catalogs as Heuer Sport 19'''FSD. With a timer function of 60s (0.2s), 30min, and 12h, as well as a stem wind mechanism and sweep second hand, the Benrus CE3 was primarily used during the approximate period of 1949. Additionally, it supports an option for a faster timer of 60s (0.1s), 30min, and 12h, along with an addition timer function.
