It has been a relatively long few months since Casio G-Shock has unveiled a unified series of watches under a color theme. The “Men in Smoky Gray” collection breaks that trend with three new popular models based on the Gulfman GW-9110, Riseman GW-9200 and finally the Mudman GW-9300. Radio synchronization is a common feature among the watches for daily accuracy. A separate contrasting color differentiates the models from one another as well. The Men in Smoky Gray collection will hit retailers in September.
