I have to say this is a certified piece of crap. I bought one and the band was too big so I set it a side so I could take a link out when I had time. Then the battery died so I set it a side until I could find my case opener since it looked like a screw on back. So I finaly located my tool and then found out the back is fake. It prys off!. So I put in a new battery and it started working so I figured I would take out a link and try wearing it. I removed 2 links and figured it would fit except the clasp broke as I was trying it on. So if I want to ware this piece of s*$% I will have to buy it a band! It still looks kind of cool but what a piece of junk. It is so big it looks like it will stop traffic.
