I bought your watch (PIONIER Florida Diamonds Automatic Watch) from Groupon on Apr 1st, 2015 and I just received it  on Apr 29th,2015.  Upon opening the box, I went ahead and followed instruction to set the date and time for the watch. To my surprise and disappointment. I discovered the the date button was actually defective.   When I pressed the date button (top right corner of the watch), the date did change alright from 00 to 21, then instead of going to 22, it has jumped to 31, then 32,33,34 and went to 05,06,07, 08, 09 then went back to 00.  The above sequence will then repeat itself consistently if I continue to press the date button.
