This works! Loosen the bezel all the way. Pressing the bottom button, press one time the topmbottom and see how the chrononhand corrects by one second towards zero. Do it again and have it reset. Tighten the bezel. Thats it
I have owned two Tag dive watches. They both have issues with the stem. You have to press it in very hard, then turn it counter clock wise tll it pops out, then you can set the time, which needs to be done (at least on these two) on months with different # days. If the stem won't move, place a few drops of "3 in1" oil, or even olive oil on it, give it a few minutes, dry off the outside, then try again - it always works for me. When pushing it back in, turn it clockwise. The next time you set the time, it'll be ++ easier.
