G-SHOCK GMW-B5000BT — FULL METAL, Black Bezel
FULL METAL / 5000 Series / Made in Japan / Released October 2025
The GMW-B5000BT carries on the octagonal form of the original G-SHOCK DW-5000C in full metal form. Black stands out against silver to emphasize G-SHOCK's signature toughness, in a monotone design that pairs easily with a wide range of styles. The top bezel gets a mirror finish, and part of the glass is silver vapor-deposited to add refined sparkle within a tough style. The stainless steel bezel is shaped three-dimensionally through forging, cutting, and polishing, and a fine resin buffer is set between the bezel and case to deliver full-metal shock resistance. The metal band pieces carry a dimpled texture that carries forward the resin band design of the original model. Made at Yamagata Casio — the mother factory that created the original G-SHOCK — the GMW-B5000BT also uses an airtight screw-back case.
Multi-Band 6 radio time correction (Japan, North America, Europe, and China) combined with Bluetooth connection to the CASIO WATCHES app keeps the time accurate at all times, with automatic time correction, world time for approximately 300 cities, Time & Place location logging, reminders, and phone finder, all backed by stable Tough Solar power.
