A key segment from Casio G-Shock's spate of October releases takes the form of the Black and Gold Master of G Series. The trio is made up of three analog models -- the GWN-1000GB-1A Gulfmaster, the GWG-1000GB-1A Mudmaster and GPW-1000GB-1A Gravitymaster -- all known for their rugged durability and finished in basic black with metallic gold accents. All three feature G-Shock's signature Tough Movement, Smart Access Crown and Tough Solar. Look for the Black and Gold Master of G Series to hit select G-Shock retailers in the coming weeks.
