Certina Watch DS-1 Big Date C029.426.16.051.00. Timelessly elegant and sophisticated at once, the DS-1 Big Date easily unites alleged opposites. An understated color gradient lends character and depth to the domed, sunray finish dials. Dark blue darkens at the edges into black, while silver gray shades into anthracite. Facetted wedge indexes, long Dauphine hands and a big date at 6 o clock ensure absolute clarity. A sapphire crystal at the back of the 41mm stainless steel case provide maximum transparency. The watches are available with a precious stainless steel bracelet or calfskin leather strap, the latter is particularly easy to remove thanks to its quick release spring bars.
