Casio CRW001-1 50th Anniversary Ring Watch Casio G-Shock GA100BL-1A Analog-Digital Shock Resistant Watch Through its domed sapphire crystalWe celebrate Casio Watch's 50th anniversary by bringing back the very first ring watch. A whole new style of digital watch both practical and playful thanks to a miniature module and advanced metalworking technology. Creating a ring sized, full metal version of the Casio watch's complex form is no easy feat. To make this possible, we needed to use a special method of metal processing to inject a mixture of fine metal powders and resin into a mold.
