News just in via forum member Deaks and the Casio UK facebook page of an all new Master of G spotted at Baselworld 2013.
No details other than the image really. Looks like an all new Master of G with triplr sensor technology - this would be the first true ABC G-Shock. If this model ever sees series production the G-Shock Rangeman is sure to be popular!
