Automatic problems are movement problems first
Rate, reserve and winding complaints should be separated rather than assuming every issue requires a complete overhaul.
Parts availability shapes the repair
Common consumables and movement work may be practical while model-specific exterior parts can be harder to source.
We keep the repair sensible for the watch
For an affordable mechanical watch, the repair should balance labor, parts, originality and what you want from the watch.
Vintage Orient depends on the exact movement
Older Orient movements may need donor parts, and originality can affect the repair and estimate.
