Hello, I am a self admitted watch hack. I've been buying watches off the bay for 18 years. I search vintage watches under $40.00 every day. I can do everything you can do without a staking machine. I have over 800 watches, with the average purchase price of $15.00. I'm a, spin it down in lighter fluid, oil it, and your good to go type of watch hack. I would never touch a watch worth over $500.00. I like to replace stems, replace and polish crystals, main springs, hands, and I have painted dials with spry can, then scrape off the numbers with an exacto knife under a microscope. I may start to sell them when I retire. I like to restore diver watches (one jewel wonders) from the early 70's. I'm just now starting to build asian 7750 chronographs, if I can find a good looking cases. I'll post some pictures when I learn how to.
