    Screw down crown question

    Hi,

    the screw down crown on my Tag Heuer Formula 1 screws in to a slightly different position than earlier. The position is further in the direction of screwing it down (you can see it by the logo on the crown) .
    Is this something to worry about?

    Thank you

    If you have been cranking it super tight in hope of a better seal the seals themselves will become compressed due to overtightening. I've owned 2 Aquaracers, kinda still do because I gave one to my brother so it's still in the family...…….. Both new watches, never overtightened crowns, just snug will due and I'm a fishing guide who gets them wet a lot, no leaks ever.

    Welcome to the forum :)

    Thanks.

    That might be it. What about the watertightness, is it compromised with compressed seals?
    I would not want to send it for service before due date if the compreseed seals offer watertightness

    The only way to tell if your watch is water tight is to have it tested. If, and that's a pretty big if, you have a quality watch repair in your town they will have a pressure tester. Unless you plan to submerge the watch for a period of time I way trust it with the crown tight. Remember I said tight not cranked down till the sap is squeezed out of it.

    I can't say that overtightening is the cause for the change in the closed position but it is the likely cause. When you think of it over tightening any thing is usually a bad idea. Even the lugs on your auto's wheels have a torque designation turn them too tight break a hub stud...…….. Your watch is no different, when you screw in / down a crown snug will do it.

    gotta be careful lol. some places will damage your watch while water testing, and then you'd have to come back to them to have it fixed. Seen that happen plenty. Having the o-ring replaced isn't that big of an ordeal either.

    You're welcome, I didn't mean to scold about the tightening thing. I've worked with many delicate type items throughout my life and found that sometimes the most common cause of a failure is a person trying to do something just a little too well. You should add a picture of your watch to the thread since I feel like I know you now :)
