The Bulova 11AOC watch movement is an open face calibre featuring a stop function with a pillar wheel. The pendant is mounted on the movement. The calibre signature of early models is poorly recorded, resulting in limited information available. Notable functions of the Bulova 11AOC include a timer with 60-second increments (with accuracy up to 0.2 seconds) and a 30-minute capability, both operated by a pillar wheel. Optionally, it can also measure time in 30-second intervals (with accuracy up to 0.1 seconds) and 15-minute durations. This movement is stem-wind operated and includes a sweep second hand. It was predominantly utilized around 1930.
The Bulova 11AOC features the following functions:
- Option: 30s (0.1s), 15min
- Stem wind
