    Date not lining up

    Hello,

    I wanted to put in a black date wheel on an NH36 movement. I replaced the day wheel to work in an SKX007 mod and that lines up correctly for a 4 o'clock crown. However, I can't get the date wheel to line up. The day and date wheel function well but the date sits high. Thoughts?

    Appreciate any help.

    Here is the part I used

    The date wheel is different for the 7S26A & B models vs. the C model. If you have an older movement, you'll need to source the older date wheel.

    I actually have a black 7S26B date wheel if you're looking for one. PM me if you're interested.


    EDIT: Never mind it looks like you have the opposite problem. The NH36 takes the newer date wheel design. Looks like you have an older 7S26 date wheel and you need to get the one for the 7S26C or NH3 movements.

    Love this doc. Thanks!

    But it looks like you don't have the part numbers for the black on white date wheels for the C movement.

    For NH36 white on black date wheel, I used part number 878 207.

    It's there, I have corrected the alignment. Make sure you hard reload the document.

    This is an excellent resource. Thank you! Now I have no idea where to source this part. I've looked on the bay and Google search with no luck. Thoughts?

    Try Cousins UK, or get a donor watch / mov't. The jumper can also be filed to align, but's delicate work.
