I almost always deal with buyers or sellers at banks, whether day or night. Why? Because there are many CCTVs around, in case of any problems. Another watch enthusiast that I met also shared that he was robbed of his watch once. This chap asked him to meet at a cafe, then when he was starting to show the watch, another chap walked by and just snatched the watch and ran off. The owner ran after the chap that snatched his watch but couldn't catch up; and when he returned to the cafe, the "buyer" had vanished with the watch box and manual.
