Join the G-SHOCK 40th anniversary celebration with a very special, limited edition collaboration with the renowned Japanese bag brand PORTER. True to the toughness-driven identity of G-SHOCK, this special edition gives the full metal analog GM-B2100 a unique aged finish, adding a vintage touch to the octagonal form inherited from the design concept of the very first G-SHOCK, the DW-5000. Red, blue, and gold accents on the dial also pay homage to the G-SHOCK debut.
