Casio Timeless Collection CRW-001JB-9ER watch

Gold-colored steel Casio Timeless Collection ring watch with brick-patterned dial and rhinestones

This ring watch is a collaboration model by Casio and the Colombian artist J Balvin. The dial of the gold-colored steel case is decorated with a brick pattern, and there are rhinestones above and below the LCD display. J Balvin's flower motif is engraved on the case back, and the watch comes in a special gold brick-patterned package.

The digital display shows the time, calendar, dual time and a 1/100 second stopwatch, and the watch has an alarm. The LED backlight makes reading easier in the dark, and the Time Flash function flashes the display to signal an alarm and the top of the hour. The case measures 25.2 × 19.5 × 6.2 mm and weighs 16 g. The ring's inner diameter is 20 mm, and the two included adapters can reduce it to 19 or 18 mm. Water resistance of 30 m is enough for hand washing, rain and sweat, but not for swimming.
