I've gathered most of what I need for a 5500 Explorer franken: a 1500 case, Yuki Dial, Gen 7835 bracelet, and a 2846 movement. I have run into two problems: I'm having trouble finding a no-date crystal (i'm just using the cyclops one that came with the original case until I find a solution), but what seems to be the major setback is that I have everything assembled, but when it comes time to put the stem in, it keeps mucking up the keyless works. I can remove and insert the stem just fine outside of the case, but as soon as I line everything up it goes kaput. I've done and redone the keyless works several times, and every time I go to put it in the case, the same thing.
Any suggestions?
