I have a Tag professional with CL 1112-0 / hp0626 on the back. Anyone know how to get a manual for it? I admit to not having a clue as to how to operate the buttons for the chronograph. The second hand also doesn't turn. Oddly, I was able to push a couple buttons and it started turning. Now it's back to not turning and I can't get it to start. Otherwise, it keeps perfect time.
