For G-Shock's 35th Anniversary, Casio and Porter have teamed up to create a special edition kit for the all-metal 5000 series timepiece. Porter will be selling the black version of the watch with a custom case that's designed to hold five watches. If you're not up to date on the latest iteration of the 5000 series watch, Casio has created a stainless steel model with the same look and feel and a few new upgrades such as Bluetooth connectivity for automatic time adjustment via your smartphone.
