Seiko 7009-3040

What you're looking at

Case, crystal and dial are all in very good condition.

What I know is wrong with it

The movement runs, but the amplitude is low and climbs the longer it runs — the signature of congealed oil rather than mechanical wear, so it needs a service before it will keep time reliably. Rate and beat error are not yet recorded.

No watch here has been pressure-tested. A period WATERPROOF or WATER RESISTANT stamp says nothing about the seals today, so treat every watch on this site as not water resistant.
