The Bulova 11ANC is a mechanical watch movement with a bimetallic screw balance and a stem mechanism without a setting-lever spring. Its bridge shapes may vary from the ones shown in the Ebel 8.75''' model. It shares similarities with other Felsa movements such as the 158, 159, 185, 208, 212, 220, 238, 246, 251, 259, 261, and 277, although the specific differences are unknown. The Bulova 11ANC movement is manually wound, features a sub-second hand, and was commonly used around 1925.
