A full-metal Porter sequel

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 symbolizing 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.
