I had the Green/Blue version for about 18 months and loved it. The build quality was really good for a Microbrand and they regulate the Soprod movement, with mine having run at +5 secs per day. It is worth pointing out that it is an office rather than true GMT, if that matters to you. I have a Rolex 16710 and whilst it wasn't at that level of quality, it punched above it's weight. I sold it on e-bay a month ago, as I was downsizing my collection, it wasn't getting worn much over the past 6 months and I have 16710. Hope this helps........
