Features 18mm lug width with convex end (凸口) that seamlessly integrates with the square case contours – eliminating the unsightly gaps common with flat-end straps.

The ultimate retro upgrade for your classic square G-SHOCK – transforming your digital watch into a vintage-inspired statement piece.

Premium Vintage Calfskin Leather – Crafted from genuine 头层牛皮 (top-grain calfskin) with a vintage, matte finish – delivering a sophisticated retro aesthetic that complements the square case design. The leather is naturally breathable – cooler than resin in summer, warmer in winter. Soft, comfortable, and develops a beautiful patina with wear – the more you wear it, the better it looks.
Convex End for Seamless Fit – Features the signature convex/curved end (凸口) that matches the square G-SHOCK case contours. Ensures a flush, OEM-quality fit – no awkward gaps or protrusions. Unlike standard flat straps that leave gaps between the case and strap, this convex design creates a seamless integration that looks factory-original. Available in Black, Brown, Tan, and Khaki.
