Had two Aquaracer 500M's in the past, a silver quartz and black auto, both shown below. Probably the last Tag's I'll buy. I like many of their designs but aside from the Grand Carrera line, quality is pretty poor. My 500m auto had a stripped crown (common problem) and the overall build quality was kind of chintzy. Also had an F1, really cheap construction, but at least they're priced accordingly.
