Casio CRW001-1

The Casio CRW001-1 shrinks the brand's classic square digital watch into a stainless steel ring, with case, band and ring formed as one piece. A three-button module and 7-segment LCD provide time, date, dual time and a 1/100-second stopwatch, with an LED backlight and a pulsing light effect. It is water resistant, uses a replaceable battery and ships with two sizing spacers, suiting collectors of unusual Casio designs.
