PURCHASED FOR MY ROLEX AUTOMATIC, SEEMS TO DO THE JOB, WHICH IS ALL I EXPECT. I FOUND THE INSTRUCTIONS RATHER INCOHERENT AND DIFFICULT TO UNDERSTAND, HOWEVER, SOME THINGS ARE OBVIOUS WITHOUT THE INSTRUCTION, SO I MUDDLED THROUGH. OVERALL, A DECENT PRODUCT.

UPDATE, IT IS NOW 2/ 2014 AND THOUGHT I SHOULD LET POTENTIAL PURCHASERS KNOW THAT THIS DEVICE SIMPLY STOPPED WORKING AFTER 13 MONTHS- WE TOOK IT TO A LOCAL MAN WHO REPAIRS WATCHES AND THESE REWINDERS TOO AND HE ADVISED US NOT TO BOTHER- IT WOULD BE CHEAPER TO BUY A NEW ONE AS THIS ONE WAS VERY CHEAPLY MADE. SORRY I TOOK A VERY LONG TIME TO REPORT THIS. I WASN'T AWARE YOU COULD EDIT A PAST REVIEW.
