Casio is releasing three “Love The Sea And The Earth” watches to celebrate the 25th anniversary of the first collaboration with the International Cetacean Education Research Center (a.k.a. ICERC). The many collaborations with ICERC over the years have produced some of the most memorable and collectible limited edition G-Shock watches.
