The O-Ring Watch displays the hour in an updated analog manner with markings that cycle its face; however, digital technology is what makes this timepiece tick and your immediate clue might be the absence of the dial's middle.
Eugeni Quitllet's concept for Fossil has a shiny silver circumference that with a smaller ring to define the circular gap in the center. The face of the watch comprises a fairly thin loop around which digital black markings revolve. As 3, 6, 9 and 12 are approached, the O-Ring Watch reveals the numeral as a negative to assist you in discerning the hour. Once a full 60 minutes has passed, the chronograph switches from black to white once more to restart the count at noon and midnight.
