Are you using a 1570 from a vintage 36mm DateJust (i.e. ref 1600)? Or from a 34mm Date (ref 1500)?

If you got the movement from a 1601, you may need to modify the ring that secures the datewheel to the movement...

RYM - Although your case is slightly more accurate than the MBW, read the end of this post. It explains what I had to do to get the 157x to fit into my MBW case.

You have to reduce the size of the ring in order for the movement to fit the case correctly. You can use a file or dremel tool to do this, but it would be best to use a lathe to turn the correct (and precise) diameter....

ok, let me see if I understand, I reduced the size of the ring above it can do it with sandpaper?

In my case, I was building a watch without a date, which is why I had to modify the calendar ring. Since you are building a watch with a date, it may not be a good idea to modify it. I would check with the seller of the case (Yuki) & ask what he recommends since the case was designed to fit a 1575.

Just curious, but doesn't the no-date 1570, 1520, not have the seating ring installed? The dial seats on the main plate?

With the Yuki case, yes, the ring would need to be replaced or modified in order to fit the 1570. The OD of the ring is 26.2mm on the 1570 for 1680. Probably easiest to remove the ring, and fit the dial to the ring, then trace around with a marker, or scribe. Then you can file or grind to the mark. You can test fit without reinstalling back on the movement.
