Gloss-white lacquer meets jet-black contrast. The Circuit Chrono Arctic brings polar clarity to its pit-lane DNA: a bright white dial framed by a black tachymeter bezel and matching black sub-dials. Polished steel markers sparkle against the ice-cool backdrop, while a discreet flash of red on the “DAYTON 60” script keeps adrenaline in view. Screw-down pushers seal the case, and inside the VK63 meca-quartz hybrid delivers mechanical-feel timing accurate to one-fifth of a second. Flat sapphire, brushed steel, and crisp colour contrast, ready for winter rallies and summer rooftops alike.
