On this front loader Seiko. The crown came loose from the stem. Since it’s front loader I had to remove the bezel, crystal and movement ring to release the stem. I have watchmaker mats to work on watches. Check out my mat an old wash rag. The good part is it worked out fine. No lint under the crystal or dial. Thank God for the blower that work great a few pumps under the crystal and on the dial good to go That funky strap had to go. Strap change was in order. Now the Seiko is better than before
