The Baumgartner 628 is a mechanical watch movement that features a jewel bearing for the barrel, enabling smoother performance. It employs an indirectly driven minute hand, allowing for a large balance and a low-profile design. This movement incorporates various functions, including automatic winding, a sweep second hand, and a date feature that can be quickly adjusted by repeatedly pushing the crown. The Baumgartner 628 movement was primarily utilized in watches produced around 1972.
