Casio has teamed up with Surfrider Foundation to celebrate 25 years of protecting our oceans, waves and beaches by rolling out the limited edition G-Shock X Surfrider Foundation collaboration watch, also going by its model number G5500SRF-1. Each purchase will see a portion of the proceeds going to the said organization as they continue the good fight. This eco-friendly watch will come with Non-Stop Tough Solar Technology, making sure time will never stop for you due to a dead battery. You will find the Surfrider Foundation logo in several places – in the backlight and back of the face, name on the band and clasp. Other features include the now standard 200M water resistance and shock resistance, five daily alarms, countdown timer, 1/100 second stopwatch and 48-city/29 time zone world time. Being a limited edition timepiece, it will be out next month for a surprisingly affordable $130.
