Outstanding!
This was the first time I had used Watchfinder and they were outstanding to deal with. The whole deal was very easy and the watch was exactly as pictured and described. In fact the watch was in even b...etter condition than suggested - like new! I put it on my timegrapher and that also gave an outstanding result. I will definitely be using them again. read more
