What Kind Of Watch Is This: Big Sean Edition

The watch he is wearing in all of these photos looks amazing. I've been told G-Shock Database or FLuD, but that's not it. Please leave a comment giving a suggestion to what it might be and where I can get it.

UPDATE: According to Big Sean, the watch is a Nooka/Garbege Zub Watch. Only 250 were made and it's sold out. I appreciate the effort from Sona Doshi who co-runs both the onenecktwochains.blogspot.com and weknowbigsean.wordpress.com websites. Thank you to Big Sean for answering the question and showing that he hasn't gone and wouldn't dare act Hollywood (Song Reference). Thank You.
