I have never been a big fan of the 5513 with the nipple dial, but with this vintage tritium color the watch looks just great!
The 5513 is a perfect base to do a restauration on, as the basis is great and the main problem is dirt.
This is a watch I would go for too...
It got the old twinlock crown, the old clasp, the case is in good shape. Really nice watch...
I would just clean it, look for a nicer inlay, softly reshape the case and you are good to go... big love...
Just to make me totally blown away: how much did you pay for the 5513?
