Winding Stem question

[Zhaodan920]

Hi everyone, I have a meters first 5513 with a damaged crown that I'd like to replace. Couple of questions:

1. I already have the replacement crown, will I also need to get a new stem?
2. If so, does anybody know the correct stem I should be using? (part no.)

Thanks!

These should be the possible part numbers for a 5513.
movement calibers: 1520-1530
crowns: 700-702
stem: 1326L

source: movement/crown Rolex R.20 Oyster Catalog stem: C&E Marshall Watch Material Catalog.

1326L is marshall’s own catalog part # for the stem.

Rolex part number is 1530-7869

And yes you’ll have to cut these to size.

Reviving this thread. Part number is 7869, but does anyone know the proper length to cut these too? I have done this before on other watches and it is a bit of a pain trial and error. Wondering if anyone has a proper sized winding stem from a 5513 that they could measure overall length. Thanks!

Easiest approach if you don't get an exact number would be to remove the old stem and remove the crown. Using that, just measure the size that you need.

Also, after cutting it's good to gently run the end at an angle in a rotating manner across a sand/grinding stone. Typically when you use cutting pliers you create a wedge with sharp corners that could get pushed out beyond the diameter of the threads. This needs to be removed before you wind the new crown on.

Lastly, I would recommend a drop of non-permanent loctite between the two.
