Heat Gradation | CASIO INDIA


Evoking the colour gradation from cold blue to red hot
seen in a sports car’s titanium muffler

A mechanical-face design accented by colour gradation that evokes the temperature spectrum,
a unique phenomenon seen when the titanium mufflers of sports cars get hot.
The beautiful spectrum, shifting from blue to red, gives the watch a look of sporty assertiveness.

    Colour inspired by the heat gradation
    of hot titanium mufflers

    When exhaust heat makes a titanium muffler change colour, a beautiful colour gradation appears, from cold blue to red hot.
    We’ve captured this phenomenon here, along with a brilliant gold tone, for a design inspired by the love of car tuning.
