7S26 does not hand-wind
A 7S26 that does not wind from the crown is not necessarily broken. The original 7S26 is an automatic-winding movement without a manual-winding mechanism. If the watch will not start or build reserve through rotor motion, that is a different diagnostic question.
Common 7S26 complaints
Stopped after sitting, starts only after vigorous motion, short power reserve, major gain/loss, inconsistent rate, noisy or ineffective automatic winding, date/day setting issues and watches that have simply never been serviced.
What we look for
We separate regulation issues from movement-condition issues. A regulator adjustment cannot correct every low-amplitude, dirty, worn or damaged movement. The actual service decision comes from inspection.
Service versus replacement
Depending on the watch, movement condition and originality, the best option may be a full service, a targeted repair or movement replacement. We explain the options before any work begins.
