We previously reported on JaysAndKays’ metal strap adapter kits with black PVD stainless steel bands for popular G-Shock models and now they are also offering metal strap adapters for the full-metal G-Shock GMW-B5000 series (ebay.com). The adapters include the necessary tools to remove the old bands and install the adapters. The adapters are available in 20mm or 22mm sizes and will fit one-piece or two-piece straps or bracelets.
Below is a GMW-B5000 with the metal strap adapters and a leather band installed. JaysAndKays also sells one-piece and two-piece leather bands on eBay.
JaysAndKays is a popular aftermarket supplier and also sells straps and bullbar face protectors at its eBay shop.
JaysAndKays products are also available at Etsy.com.
