The International Durowe 589 621 watch movement was developed in 1955 and features a detached manual wind mechanism with wheels made of beryllium bronze. Despite its short production run of approximately one year, two variants of the manual wind gear and two balances were produced in parallel, suggesting an experimental nature. The movement encompasses various functions including automatic winding, sweep second hand, date display, and a calendar. Its period of use is estimated to be around 1955.
