    Help with slow Tissot

    Hello friends!

    New to the forum and new to watch collecting in general. Maybe some of you will have an answer to my question. I received a 1967 Tissot Seastar in pieces the other day. By pieces i mean the movement, case, glass, and two screws. After putting everything back together I am finding that the movement is losing time. After a good wind and letting it sit, it keeps great time for about an hour then the movement starts losing time and ends at a half an hour behind compared to my other watches. The funny thing is, it keeps great time after it loses that initial half hour. Any ideas or suggestions to why this is happening?

    Some observations to help:

    -The movement is a Tissot 782-1 Unadjusted 17 jewel manual wind


    Thanks for your help

    Just a hunch, but it sounds like the cannon pinion needs tightening, or is worn. When you set the watch, does it feel kind of like they're moving way too easily,

    or do they jump a bit when you push in the stem?

    Again, just an "O"pinion...........heh heh.

    Marks55,

    This is exactly what is happening. So how does one tighten a cannon pinion?

    If the second hand isn't losing time then it sure is the cannon pinion. You should mount the cannon pinion on a shaft of some kind and it should be snug but not tight fitting then one can use a set of round nose pliers and pinch the cannon pinion so it fits tighter.

    Cheers Shum, might give it a go i paid 2 euro for it, and if i destory it the bracelet is worth that - You have to remove the dial though, i assume? Not sure i can see how it's secured on my watch.

    My 2c, check the part is available on cousins or jules borel etc first. It can be easy to go too far, particularly if the pinion is worn. And u don't want to break the pinion and THEN realize it's a rare part with none for sale anywhere!

    On most movements from this period you will find two tiny screws on the side of the movement that one loosen, these screws are pushing against the dial feet from the sides so don't just pull the dial off as this will break them off.
