Start with the movement
Simple, widely supported movements are usually easier to quote and schedule. Proprietary calibres, integrated complications and specialized finishing narrow the service network.
Separate routine from corrective work
A routine overhaul, water-damage repair, bracelet restoration and replacement of damaged cosmetic parts are different jobs. Ask what the estimate includes.
Price the first 24 months
For an undocumented pre-owned watch, assume the possibility of service sooner than the seller’s confidence suggests. Keep a reserve instead of spending the entire budget on the watch.
Protect originality intentionally
Specify whether polishing, dial replacement, hand replacement or lume work is permitted. A service centre’s default may not match a collector’s preference.
Use service friction as a buying signal
A medium-friction watch can still be a great buy. The problem is paying a low-friction price while inheriting a specialized or deferred-service example.
