This unique edition elevates the toughness and resilience that G-SHOCK is known for, giving the full metal analog GM-B2100 a vintage-inspired aged finish. The design maintains the iconic octagonal shape of the original DW-5000, enhanced with striking red, blue, and gold accents on the dial. The bezel and band are ion plated in black and then partially removed to create a well-worn, rugged texture. The hands feature a luminescent beige finish, completing the timeworn aesthetic. The watch is adorned with the 40th-anniversary logo by Eric Haze on the case back, and the buckle proudly displays the Shock-Resist mark, symbolizing G-SHOCK’s unwavering commitment to durability. As part of this limited-edition set, G-SHOCK and PORTER have crafted a unique collector’s bag. Designed in the GM-B2100’s octagonal shape, the bag is made from water-repellent Ventile fabric and features a leather tag stamped with the G-SHOCK 40th-anniversary mark. Founded by master craftsman Kichizo Yoshida in 1935, YOSHIDA & Co. introduced the PORTER brand in 1962 with the philosophy of putting “heart and soul into every stitch.” This collaboration reflects PORTER’s dedication to quality and craftsmanship, making it a perfect match for G-SHOCK’s legacy of toughness. Don't miss this chance to own a piece of history with the G-SHOCK x PORTER limited edition set—where timeless design meets unmatched durability.
