I regulated it one day, and then a week later pulled the stem out completely after letting it run out of spring, it warped the keyless works beyond repair so I hunted for a replacement seagull st6(the movement that some folks claimed Timex used) The closest that I found was a Sea-Gull TY6DSK movement the dial and hands fit but I had to modify a screwdriver to fit the dial feet screws, I also hat to clip and file the stem at both ends to install the original crown as the original stem would not work in the new movement. I am looking for a new seconds hand as it broke on installation, my error was not using the right tool. The new movement is upgraded somewhat from the originals 20 jewels to 23 jewels...probably won't make a super huge difference.
