Casio has bolstered its Pro Trek line-up with a collaboration with Japanese outdoors brand, Nanga.
The limited-edition PRW-6630NA or Pro Trek Nanga was a designed jointly by the two brands with “outdoor and environmental enthusiasts alike.”
Biomass plastic – derived from castor seeds and corn – forms the watch’s case, strap and caseback, while it is presented in sustainable packaging along with a reusable Nanga eco bag.

The khaki green and beige colors used throughout are taken from Nanga’s Aurora light down jacket and its Level 8-23 Aurora light sleeping bag.
Nanga’s logo features on the dial and caseback while the brand’s “Believe In Your Adventures” tagline appears on the watch’s keeper.
