Traditional tsuiki Japanese craftsmanship. Each article a work of rare beauty that reflects the personality of the artisan who created it. Shock-resistant full-metal design with Bluetooth® GPS radio-controlled solar-powered timekeeping Introducing a new model from MR-G, the top of the G-SHOCK line, that packs Bluetooth® GPS radio-controlled solar-powered timekeeping into an elegant design featuring a hammered finish bezel. Traditional tsuiki metal hammering has been used in Japan for centuries in the production of armor, copperware, and other metal implements using a mallet and special chisel that leave marks that create a distinctive pattern on the metal. These marks resemble the scales seen on black dragon drawings and make each item a work of art. The painstakingly hammered patterns of the metal reflect the personality of the artisan who created them, and identify the handmade nature of each item. This traditional Japanese aesthetic sense is applied to a shock-resistant, full-metal body that houses a 3-Way Connected Engine for accurate timekeeping virtually anywhere in the world. The result is absolute toughness and absolute accuracy that is distinctively MR-G. *GPS radio-controlled solar combines CASIO's own solar power charging system, positioning using a Global Positioning System (GPS), and reception of time calibration signals around the world. The MR-G form combined with traditional Japanese beauty. Capturing the very soul of the artisan who created it. Hammered finish Bold and daring, refined and delicate, the hammered finish of the bezel is created using a traditional Japanese technique known as tsuiki. A pattern that interweaves the skill and experience of the artisan who created it reflects the relative force applied with the chisel and mallet used to deliver each strike. Each pattern is unique and each individual item exudes the personality of the artisan who created it.
