Input: Unfortunately, I did not know to turn down the stem before going in the water! I think that some water got in, and now the hour hand is always ahead of the hour. I tried to return it to Amazon, but my 30 day return period expired, when I was in the hospital.

Tighten the stem before going in the water with this watch!!
