THIRD Searchlight plays with light and reflection to display time. The hour is represented by the light shining from the underside of the dial onto the inner wall of the case and the minute by the floating luminescent white dot. The minute hand constantly chases the hour hand, hence comes the name, Searchlight.
SECOND Blur watch features a frosted crystal. The hour and minute hands are represented by two dots with height difference; the higer dot, the hour hand, is less blurry compared to the minute hand because of its proximity to the surface. Pebbles.
FIRST Dial is missing lots of things. It does not have a crystal, crown, or hands. The missing parts' functions are fulfilled by two rotating discs each with hour or minute marking. The circles rotate counterclock-wise, and the current time is indicated by the line on the 12 o'clock-strap. Draw an imaginary line down to the center of the disc and read the hour and minute marking. To adjust time, press middle disc and rotate the outer circle like a dial.
