Casio CRW001G-9D Digital Ring Watch – Gold

An astonishingly compact digital watch designed to be worn as a ring, the Casio CRW001G-9D uses metal injection moulding to create its detailed stainless steel body with a gold ion-plated finish. Its miniature seven-segment LCD displays hours, minutes, seconds, month, date and day, while three small buttons operate dual time, a 1/100-second stopwatch (up to 59 minutes 59.99 seconds), LED backlight, 12/24-hour format and a February-28 auto-calendar. Time Flash can pulse a light at a chosen daily time or on the hour, though the light may be hard to see in bright surroundings. The ring offers everyday water resistance, approximately ±30 seconds-per-month accuracy and a replaceable SR621SW battery rated for two years. The standard ring is Japanese size 22, with supplied spacers for smaller size 19 and 16 fits; these are adjusters in one product, not selectable variants.
