    Automatic gaining 9 minutes per hour

    I have an Accurex Delux 21 jewel auto swiss movement and aside from band looks almost new. I had it serviced 20 odd years ago, put it in a draw, and forgot about it until recently. It is gaining approx. 9 minutes per hour. Is this an easy fix for a watchmaker or am I wasting my time and money .

    Your watch might be magnetized, but it's also possible that it's overdue for a service.

    Even though the watch has sat in a draw unused since its last service? How long between services for an automatic would you recommend.

    If it runs at all, a basic service will put it right (unless the springs are corroded), and a basic service is necessary at this point anyway. The service will cost one to three hundred dollars, depending on the watchmaker and the parts needed. If the watch is not worth that to you, then maybe put it back in the drawer. A 21-jewel movement could be one of several, but if actually 20 years old (ca. 1994), is most probably an ETA 2892, which would make it a nice watch.

    After 20 years, even if it was unused, there's a good chance that the oils have migrated from the jewels or coagulated.

    After a decade, the oils are dry, but they were probably gummy and dirty for a few years before the end of that decade.

    Thanks for replies .I had it serviced 20 odd years ago it was actually my fathers watch and I would guess circa. 1960-1975. The only number on back is 3090
    Aside from gaining time runs great . Actually what drew me to it again was how smoothly the second hand sweeps.

    If it's your father's watch, definitley spend the few hundred $ and get it serviced. Then you can enjoy it for another 20 years.
