Nooka - Zub Zan NG 40 - Unlike Nooka’s other watch faces which re-conceptualize how to tell time, the Zan offers a traditional analogue display. While simple, the Zan’s subtle innovations in form and feel compliment the Zub 40 bands to convey the Nooka philosophy for a wider appeal to a larger audience. This line of watches will allow the user to personalize any of Nooka’s Zub 40’s with combinations of the many colored bands that the line will offer. The Zub 40 also introduces a new buckle that folds into itself, getting rid of the extra length of the band, minimizing its profile for added comfort.
