Dial Washers (Foils) for Hour Wheels

Dial washers (foils) ensure that the hour wheel is held securely in place within the movement and engages cleanly with the pinion of the motion-work wheel. Their slight pre-tension gently presses the hour wheel toward the dial side, allowing the gear teeth to operate smoothly and without unwanted play.

If this washer is missing, the hour wheel may not remain properly guided — which can lead to slipping hands, inaccurate time display, or inconsistent tooth engagement.
