1. Preparation:Place the hands setting tool on a stable workbench – ensure the base is secure
2. Select Stake:Choose the appropriate cylinder hollow stake based on hand hole diameter and pivot size (0.30/0.50/0.70/1.15/1.50/1.70 mm)
3. Install Stake:Insert the selected stake into the stake holder – ensure it is securely fixed
4. Position Movement:Place the movement with dial installed in the center of the base
5. Position Hands:Align the hands (hour, minute, seconds) onto the movement pinions – lightly set in place
6. Press Hands:Hold the stake holder, align the stake with the hand hub, and apply even vertical pressure to press the hand onto the pinion
7. Check Installation:After pressing, verify hands are parallel, at proper height, and do not interfere with each other
Technique Tips:
Install hands from bottom layer up (typically hour → minute → seconds)
Use the flat nylon tip stake to protect the dial surface from scratches
The conical stake is suitable for specific hand types or angled operations
| Note | Details |
|---|---|
| Stake Size Selection | The stake‘s inner diameter must be slightly larger than the pivot diameter – ensures the hand hub seats correctly without damaging the pivot tip |
| Vertical Pressure | Maintain vertical alignment when pressing hands – angled operation may cause misalignment or bent pivots |
| Force Control | Apply even, gentle pressure – excessive force may deform hands, break pivots, or damage the dial |
| Protective Measures | Using the flat nylon tip stake can protect the dial surface from accidental scratches |
| Anti-Static & Dust-Free | Work in anti-static, dust-free environment to prevent dust adhesion on dial or movement |
| Professional Advice | If inexperienced, use under professional guidance or entrust to a qualified watchmaker |
