## FAQ
**Q1: Which color is the most durable?**
A: All three have stainless steel bases. Black and rose gold are PVD coated; the coating may wear off at edges over time. Silver is raw stainless steel and will not fade.
**Q2: Can I install without threadlocker?**
A: Not recommended. Chronograph pushers are subject to frequent pressing and vibration. Without threadlocker, they will loosen. Low‑strength threadlocker prevents loosening while allowing future removal.
**Q3: Will the watch retain its 50m water resistance after replacement?**
A: Due to tolerance variations in generic parts, the original 50m rating cannot be guaranteed. Always perform a water resistance test after installation. Conservative use (splash‑proof, no swimming) is advised.
**Q4: Does this pusher include the internal spring and O‑ring?**
A: Usually yes – some versions come pre‑assembled with spring and O‑ring, others may not. Confirm with the seller before ordering.
