The old belt on my GW-3500B broke about 6 months ago and I finally found the time to replace it. Right out of the box, the strap was quite stiff and took about a week to fully detach, but now my watch is comfortable. Almost identical to the strap that came with my watch (slight difference in buckle size/shape, but not a deal breaker at all). Be warned, this belt was very difficult to replace and I had to watch several manuals/20 minutes before I was able to successfully remove even one.
