Adjusted To Six 6 Positions

Positions for Adjusting Watch Accuracy and Timekeeping

Adjusted To Six 6 Positions

What does Adjusted in Six (6) Positions mean?

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 reason why watches are tested in multiple positions is because the force of gravity plays a role in a watch’s accuracy. In other words, a gain or loss in energy transmission occurs depending on the position of the balance wheel.

Simply put, your mechanical timepiece performs differently (has different rates of accuracy) based how it is worn or placed on the table. That is why accuracy is calculated as an average of these positions.

The 6 positions for watch regulating:

  • Dial up
  • Dial down
  • Crown up
  • Crown down
  • Crown right
  • Crown left

While these are the common positions for regulation of a watch movement, sometimes a movement is also tested in half way crown up and half way crown down positions.

How many positions are COSC certified movements tested in?

Some watches are tested in all 6 positions, but a COSC chronometer is tested in 5.

What is an “unadjusted” watch?

You may also come across watch movements that are labeled as unadjusted. This means that the watch was produced without undergoing any testing and adjusting from the factory – tested in 0 positions.

Pocket watch positions are similar:

  • Dial up
  • Dial down
  • Pendant up
  • Pendant down
  • Pendant right
  • Pendant left

You may have seen pocket watches that have 8 or 9 adjustments as well. This means they are also including adjustments for Isochronism or temperature (hot/cold).

Timing Machine Positions:

Using a timegrapher such as the one pictured, you can secure the watch head on the microphone stand and rotate the watch in all of the various positions to see the difference of rate in each. Check out the watch timing machine below (purchasing from the link helps to support this site).

Consice, to the point, easy to understand. I always wondered about the adjusted to 5 positions label on my watch mechanism. Thank you for the clarification. -benoit

So if position matters, for a lefty, does wearing a watch on right wrist result in different +/- spd than wearing on left wrist? Presume this is better than exposing watch to all the extra daily shocks of watch on left wrist of left-handed person?

Excellent, thank you very much for such a detailed, easy to understand explanation
