    Mod & Restoration Reviews (Mod/Restored Watches)
    I recently completed a case restoration on 6309 - 7040 that had a missing stem/crown tube. I have posted an article on my website describing the process. It can be found at doughking.wordpress.com It was a fun project and I am happy with the results.
