G-Shock celebrate their 30th anniversary this year. For the occasion they have teamed up with Maison Martin Margiela to create GA-300. The GA-300 is a based model, which means that it has a bigger case and an elaborate face design. The case band, display (with liquid crystals) and clock hands are held in silver. The watch also comes with a leather band, which is wearable as a watch band, or as an accessory.

The watch is limited to 3000 models. Each model will carry a unique serial number,  and will have a selling price of 300 Euro. In Margiela stores the watch will be on sale from 30th of March, and G-Shock stores will have it from 8th of April.
