Return To ShopThe Bettlach 8420-74 watch movement, introduced in 1974, features a pin-lever escapement, indirect minute hand friction clutch on the barrel, and a releasing stem accomplished by strongly pulling the crown while turning it counterclockwise. Inserting the stem is achieved by strongly depressing the crown while turning it counterclockwise. It is worth noting that there may be additional variations within this family, but comprehensive documentation is lacking. The movements typically bear the designation of the most frequently produced variant. The codes for features are attached to this signature when the official designation is unknown. In terms of functions, this movement is a manual-wind chronograph with a 60-second measurement and a 15-minute measurement, with cam switching capabilities. It also includes a sub-second display and a date function that can be quickly set by reverse setting.
The Bettlach 8420-74 features the following functions:
