Here's how to get the movement out of these kind of watches - this method also applies to Timexes with the older one-piece aluminum cases. Once you get the crystal off and the spacer ring under it, you will see a slot by the 'three'. Look through there and you will see that there is a flat spot milled into the stem. Now you will have to make a tool - really a very small open end wrench. I used a small piece of brass, but a screwdriver bit would do as well - it's just easier for me to file down brass rather than steel. The wrench must have a 1mm wide opening that is about 1 1/2 mm dep. the whole thing should be about 3 or 4 mm wide by 1 mm (or less) thick. Put that into the slot and aound the milled out secion. All you have to do now is unscrew the crown.
