Japan will be in for a Holiday season treat from Casio this December as the G-Shock GB-6900 smartphone compatible watches will be coming out. Equipped with Bluetooth 4.0 and available in some solid color choices such as black, red, and white, the GB-6900 also boasts some other nice features.

Features include automatic location based time adjustment and notification of incoming calls and emails on your phone by way or an alarm or vibration that can be deactivated simply by tapping the timepiece.

Take a look at the first available colors after the jump.

The latest development in the G-Shock 25th anniversary celebration is this DW-5600 done by Singapore-based sneaker customizer SBTG, for whom this was a childhood dream come true. “My mom bought me a G-shock when I was about seven years old and I immediately felt like the luckiest kid in school. It was a status symbol man.” Taking a simple black base, SBTG printed the face and strap with his trademark star and camo patterns, seen across both his shoes and Royalefam clothing line.

For those of you looking to get your hands on this piece, the watch is being given away through Royalefam.com — sign-up between now and August 2nd for your chance to win. No purchase necessary. It is rumored that there are only 10 pieces in existence.

Check out more shots of the SBTG/Royalefam x Casio G-Shock DW-5600 after the hop and skip.
