Important Note
Due to the age and nature of vintage automatic mechanical movements, timekeeping performance may vary and may not meet the accuracy standards of modern quartz watches.
The movement should ideally be inspected and serviced by a qualified watchmaker if its recent service history is unknown. Vintage mechanical movements can require periodic servicing to maintain stable performance.
Although the movement is currently running reliably, this should not be interpreted as a guarantee of future accuracy or service condition.
Any original water-resistance specifications or markings should not be interpreted as a guarantee of present-day water resistance. Gaskets, seals, crystal, crown and case-back components naturally deteriorate with age.
Unless specifically stated otherwise, this vintage watch has not been pressure-tested and should not be assumed to be water-resistant. Swimming, bathing and diving are not recommended.
The bracelet should also be inspected for normal vintage wear, including link condition, pin condition, bracelet stretch and clasp security.
The Citizen-signed clasp is a changed/replacement component and is not represented as the original Seiko factory clasp.
All measurements are approximate. Please examine all product photographs carefully before purchase, as photographs form an important part of the condition description.
