Casio wristwatch G-Shock domestic genuine product full metal Bluetooth equipped radio solar black bezel GMW-B5000BT-1JF mens silver

This model features a black octagonal top bezel, inheriting the octagonal form of the original G-SHOCK model "DW-5000C" from the GMW-B5000, GM-B2100, and GMC-B2 100. The striking black against silver emphasizes the iconic strength of G-SHOCK while offering a versatile monochrome design. The GMW-B5000BT has a mirror-finished top bezel and silver vapor deposition on part of the glass, adding intricate shine to its tough style. The GM-B2100BT and GMC-B2100BT feature a hairline-finished top bezel, creating a calm metallic feel. Additionally, silver vapor deposition on the indices enhances visibility and contrasts with the dial. The stainless steel bezel is shaped through complex processes like forging, cutting, and polishing for a beautiful finish. To achieve a shock-resistant structure with full metal, fine resin cushioning material is placed between the bezel and case. The metal band piece features dimpling, inheriting the resin band design of the original G-SHOCK. Manufacturing takes place at the mother factory "Yamagata Casio," which produced the first G-SHOCK. Furthermore, the stainless steel cases of the GMW-B5000BT and GM-B2100BT utilize a screw-back case with excellent airtightness. - Shock-resistant structure - Tough Solar (solar charging system) - 20-bar water resistance - Radio reception function: automatic reception (up to 6 times/day) (up to 5 times/day for China) / manual reception, reception waves: JJY, frequencies: 40kHz/60kHz (compatible with Fukushima/Kyushu) reception waves: WWVB, frequency: 60kHz reception waves: MSF/DCF77, frequencies: 60kHz/77.5kHz reception waves: BPC, frequency: 68.5kHz *When set to a city capable of receiving home time settings, it will receive the corresponding station.
