Casio has unveiled a set of tiny rings modelled after some of its most popular watches from years gone by.
The little rings include miniaturized versions of the CA-53WF-1B calculator watch (shown above), the vintage-style gold A159WGEA-1, the sporty MRW-200HJ-1B, the button-strewn A100WE-1A, and the limited edition Casiotron TRN-50-2A, which is a recreation of the company's first ever wrist watch . There's also a sixth mystery model that's yet to be revealed, but as Casio fan site G-Central notes, its comparatively chunky silhouette implies it's a dinky G-Shock.
