You may have seen Adjusted in Six (6) Positions stamped on your watch movements. This means that the movement was tested and adjusted (or regulated) in 6 positions. The force of gravity plays a role in a watch’s accuracy, causing a gain or loss in energy transmission depending on the position of the balance wheel.
The 6 positions:
- Dial up
- Dial down
- Crown up
- Crown down
- Crown right
- Crown left
Some watches are tested in all 6 positions, but a COSC chronometer is tested in 5. There are also watches that are unadjusted, meaning that the watch was produced without undergoing testing and adjusting from the factory.
