The Knob That Needs Care
The crown is the most touched part of your watch — and the most vulnerable. Here is how to keep it working properly.
Crown Care Basics
- Screw-down crowns: always screw back down after setting — leave it unscrewed and water resistance is zero
- Push-pull crowns: push fully in after setting — a partially protruding crown can catch on clothing
- Never force: if the crown resists, check the position before applying more pressure
Common Crown Problems
| Problem | Cause | Fix |
|---|---|---|
| Crown won't screw down | Cross-threaded or debris | Clean, re-align, try gently |
| Crown feels gritty | Dried lubricant | Service needed |
| Crown pulls out too easily | Worn detent spring | Service needed |
| Crown stuck in position | Corrosion or debris | Professional service |
Crown Replacement
If a crown is damaged or worn, replacement is straightforward — most watchmakers can source correct crowns for common movements. The NH35 family uses standard crown sizes widely available.
Frequently Asked Questions
Can I oil the crown myself?
Not recommended — crown mechanisms are precise and require correct lubricant types.
How often should the crown be serviced?
As part of regular movement service — every 3-5 years for mechanical watches.
Does crown damage affect water resistance?
Yes — the crown is the weakest sealing point. A damaged crown should be replaced before water exposure.
