I've been impressed by GS for sometime despite not seeing one in-person. My only criticism, or wish, would be that they distinguished their look a little more so they were a little more set-apart from a standard Seiko, much like Credor. Here's a little photoshopping I did. If they looked a little more like this, I'd be much more willing to buy one. As it is, the current labeling would likely be a deal-breaker for me.
Anyone else? It's just that they are really special, so why not make them a little more distinct.
For the record, I still like them a lot.
