    Will an automatic speed up after "break-in"?

    I just purchased a Timex automatic and it appears to be running about 15 seconds slow per day. I know that is within spec, but I would prefer it run fast rather than slow.

    I also have an Invicta 8926 that was running 20-22 seconds per day fast. After a week it is only about 12-13 seconds per day fast. This is acceptable to me.

    If this Timex slows down further, I would be rather unhappy.

    What are your thoughts; is there much of a chance the Timex will speed up after some break-in?

    In my experience, if they do anything, it's slow down.

    Yes the common urban legend is they'll slow down.
    In my experience, they stay pretty much the same.

    I'd wear it for about 2-3 month. If the watch will continue to perform as mentioned: Take it to the watchmaker. He should easily adjust gain/loss.

    Not an urban legend....

    at least depending on the movement. 90% of the couple dozen new Seikos (7S26/36/35) I've had did in fact slow down over the first weeks, as did about half the Miyotas and a couple of the ETAs. OTOH, most of the ETAs (2824s and 7750s) didn't change much at all. Whenever I get a new (or new to me) watch, I time it for a week or so, then again the next extended period I wear it. Can't say much about the Timex as I haven't had one of the new ones, but I wouldn't feel confident that I knew how it would run until I'd worn it for a few weeks, at least.

    Have you considered buying a Rolex? That would cure all your problems because they don't loss/gain more than a few seconds per month.
