OTTA places contrasts under tension.
Black forms the base, colour sets the impulse.
Graphic lines, precise accents, and sharpened contrasts define the look. The design appears focused, graphic, and full of energy. The shape is deliberately present — not decorative, but assertive. Colour is not applied broadly, but used with intention: as a signal, as movement, as attitude. OTTA remains clear, yet never static.
From a technical perspective, the model is built on Rolf’s proven Substance foundation: high-quality materials, precise construction, and a wearing comfort that performs in everyday use.
Eyewear that shows design does not stand still — it moves ahead.
