Same thing happened to a PO I was modding for a member a while back...but it was the Silix version which have quite a thin crystal in them compared to the normal UPO.
The main differance between Reg's PO bracelet and the UPO bracelet is the width, Reg's is 20mm and the UPO is 22mm.
The UPO is available with swiss or clone ETA...you would not be able to tell which you have without opening the caseback.
