The Threaded Connection
The crown thread is the screw mechanism that connects the crown to the stem inside the watch.
Why It Matters
- Water resistance threaded crown seals against water
- Security prevents accidental unscrewing
- Durability protects the stem from damage
Types of Crown Threads
| Type | Use | Water Resistance |
|---|---|---|
| Screw-down | Dive watches | Excellent |
| Push-pull | Dress watches | Basic |
Maintenance
- Keep threads clean and dry
- Apply silicone grease occasionally
- Do not over-tighten
