I happened across a store (actually a couple since the same ones were sold in different stores) in Harajuku wth some neat watches. They were the typical watches you would expect from China (i.e., no name) but had better visual stylings. They were also about the same price as what you would get from China, that is to say < $10USD. There was a lot of selection, and many were interesting, but $10 per watch would add up quite quickly (plus they were from China so I wouldn’t expect them to last that long).
Here is one that I picked up. It hasn’t broken yet, after two weeks of wearing it daily, so that’s a bonus.
I also picked up this one.
I don’t like the design very much, but I basically HAD TO buy it because the “brand” was Kevin! I didn’t even have to engrave it.
