    It's one of the things I love about this movement----I've adjusted all of mine down to 0 or .1ms beat error.

    No but I'll write you one...

    1 - Fully wind watch, place dial down on timing machine with movement exposed

    2 - Note beat error

    3 - Move the adjustable stud carrier until beat error is as close to zero as your skill set and patience allow

    4 - Adjust the regulator (when you adjust the bear error the rate is going to change) as needed

    5 - Close up the watch and enjoy

    Adjusting beat error on any watch with an adjustable stud carrier is about as simple a task as you can do working on watches. But please be aware that if you slip, you can do a lot of damage in a second...

    Also, Omega allows the beat error to be as much as 0.8 ms on this movement. Most watchmakers will bring it down as close to zero as possible, because it's easily done, but unless the beat error is out by a lot it's not typically a huge deal really.

    Cheers, Al

    So I’ve been fiddling around with this and it seems I can’t get this right. The stud carrier(which I’m assuming is what I’m pointing at in the photo) has been moved both ways and I can’t seem to get the beat rate lower than 2.6ms. This watch was serviced recently but when I put this on the timegrapher, this is what I get. I have take it back to him to adjust and this is be best he can do.... I won’t get to the details about this watchmaker, but is it suggested I take it to someone else for a second option?

    The arrow is pointing at the carrier for the regulator curb pin and gate. That is what you move when regulating the watch. The arrow passes directly by the stud carrier which is to the immediate right of the arrow. The stud is triangular, and it is held in place by a tiny tangential screw. The stud carrier is copper coloured, not polished steel. That is what you move to adjust the beat. Should you be attempting this?

    Stud carrier is the other lever. Be very careful!

    From my understanding, both the stud carrier and the regulating lever will need to be moved the same amount because of the fact that moving the stud carrier will change the length of hairspring held in place by the regulator. Though, I might be wrong.
