The Puw 1363 is a mechanical watch movement with an automatic winding system. It features a sweep second function and is designed with a large balance and low profile due to its indirectly driven minute setup. The differences between the Puw 1363 and its counterparts, the 2375 and 2379, are not known, including the assignment to different rotors, which could involve a single part or a separate sinter-metal weight.
