Why owners notice 6R35 timekeeping
A long power reserve is useful, but it does not eliminate mechanical variation. Position, state of wind, movement condition, magnetism and regulation can all affect observed rate.
Typical 6R35 jobs
Excessive gain/loss, inconsistent rate, reduced reserve, winding problems, stopped movement, crown/stem issues and routine mechanical service.
Diagnosis before parts
Not every poor-running 6R35 needs the same repair. The final recommendation and price come after inspection.
When to send it
If the watch is suddenly running very differently, repeatedly stops or will not build reserve, tell us exactly what you are seeing. Photos and the case/reference information help us identify the watch before it arrives.
