The International Durowe 430/1 watch movement, which was in use from 1953 to 1960, features an intermediate wheel positioned between the minute pinion and the rest of the train. This design allows for a large balance wheel and a low-profile without compromising durability. Additionally, this layout provides flexibility for placing the seconds wheel either in the center or for a sub second, without requiring any further modifications. The International Durowe 430/1 movement is manually wound, incorporates a sweep second function, and includes a date feature which can be set by changing the time to 20:45-24h.
