It may look clandestine and indestructible, but the real glow of the new collaborative Frogman created by mastermind Japan and G-Shock comes from the meticulously thoughtful design details. G-Shock’s specialized diver’s watch, the Frogman, may be meant for going the depths in ocean, but after rocking skulls and crossbones a la mastermind Japan, these watches are just right for roaming the streets. Aside from the Frogman’s known technical diving capabilities such as time and radio availability for up to 200m underwater, dive log, dive time, tough solar technology and time for 48 cities in the world, the mastermind Japan collaboration glows with a violet backlight eaturing two skulls and crossbones logos that illuminate at the press of a button. A mastermind Japan logo is engraved onto the stainless steel back and the text logo is printed on the watch strap. The special watch is created to commemorate the new opening of the Ron Herman store and comes packaged in a special co-branded box. The production is extremely limited and comes only at a run of 200. The mastermind Japan G-Shock Frogman GFW-1000 is now available for order online via rakuten if you are feeling for a cool Frogman that will work just as well in water and out.
