Hi.

I was wondering if anyone has a good write up how to install a dw on a rolex 1570 movement?

Thanks.

The 1570/5 date wheel is held in place by the date index spring aka 'date jumper' and the jewels/metal discs around the inside edge of the date wheel spacer.  It is so simple that one look will be enough to see how it fits...much easier to r/r than an ETA 28xx.

In the first picture showing the date side of the movement with the date at 22...the 'date jumper' is at 4 on the date wheel.  You have to look close to see it.  The 'date jumper' supplies enough tension to the date wheel to keep it in place under the two metal discs at 1 and 10 in the picture.  The small round disc on the end of the 'date jumper' has a screwdriver slot in it to turn the disc one way or the other to center the date number in the date window.
