Infinitely changing colors, a regulator structure on a 42-part hand guilloche dial, a retrograde second and exposed mechanics set standards and embody the motto of Chronoswiss "Modern Mechanical".
The combination of traditional guilloche craftsmanship and high-tech nano-coating enables the Open Gear ReSec Chameleon to effortlessly display the chameleon's full range of colors on the dial. The changing color nuances of the timepiece and its 3-dimensional structure set standards in design and mechanics.
