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.

To replicate the aging process, the bezel and band are ion plated in black, which is then partially removed to create a well-used texture.

A luminescent beige finish on the watch hands adds the final touch, for a distinctive timeworn look. The 40th-anniversary logo designed by Eric Haze is featured on the case back, while the buckle showcases the Shock-Resist mark symbolising the G-SHOCK commitment to toughness.

For this limited-edition collaboration, G-SHOCK partners with PORTER to create a unique collector’s bag crafted in an octagonal shape that reflects the GM-B2100 design. Made with densely woven, water-repellent Ventile® fabric, this premium bag features a leather tag stamped with the G-SHOCK 40th-anniversary mark.

PORTER Master bag craftsman Kichizo Yoshida founded YOSHIDA & Co. in 1935, and went on to introduce the PORTER brand in 1962. With the company’s motto “heart and soul into every stitch,” PORTER continues to produce bags of exceptional craftsmanship made in Japan.

The brand name pays tribute to the porters who handle guests’ luggage, reflecting the respect and dedication to quality of true craftsmen.
