Time Measurement & Winding
This section provides information on the mechanical aspects of time measurement and winding.
Accuracy
Accuracy is measured within a lapse of 10 to 60 minutes from full winding, using posture 1 (Dial side up).
Posture Difference
Accuracy is measured in the following four postures:
- Dial side up
- 6 o'clock side up
- 9 o'clock side up
- 3 o'clock side up
The document shows visual representations of these four postures.
To Make Full-Winded
To achieve a full wind:
| Model(s) | Action |
|---|---|
| 90 / 91 | Turn the crown 40 times |
| 82 / 8N | Turn the crown 40 times |
| 6T | Turn the crown 20 times |
Winding Direction
The winding direction is illustrated for different model groups:
- For models 90/91/6T, the winding direction is indicated by a counter-clockwise arrow. ?
- For models 82/8N, the winding direction is indicated by a counter-clockwise arrow. ?
Setting the Time
The document includes an illustration demonstrating the procedure for setting the time on the watch movement.
