Casio quietly launched five new G-Shock watches between July and August 2026 with almost no fanfare compared to its usual heavily-promoted releases: the Mudmaster GG-B100XMH-5A, Mudman GW-9500MH-5, Gravitymaster GR-B300H-5A (all part of the Master of Horizon Gold series), the basic-digital GD-350S-1, and the surf-inspired G-LIDE GBX-H5600KI-5.
This GD-010-4JF is part of G-Shock's core digital lineup that the new GD-350S-1 also belongs to, currently in stock at CDJapan.
