I bought this watch and the instruction manual was of no use.  I called Tissot and they emailed a manual specifically for this watch.  I spent 2 days trying to get it to work.  I finally called Tissot and luckily there was a Tissot authorized service center in my area.  I asked for help on setting the watch over the phone.  The gentleman I spoke with said it was too hard to explain on the phone.  I brought the watch down to him and he set it in about 15 minutes.  I don't know how Tissot can sell a watch with such a poor instruction manual.  I returned the watch to Amazon.  They were excellent to deal with.
