Hi Bro, just my 5 cent info. Some mentioned JW@international building verification charges is $35. However, it has change to $100 instead and it will take only approximate 20 min verifying your watch subjected to no crowd. Also, they are operating on tue/Thur/Sat 12.30pm to 4pm. For transaction over weekend at least can consider them too ya.
