The Certina DS-1 reference C029.807.22.081.00 has looks inspired by the first DS concept watches of the 1960's, but inside its 40.00mm Stainless Steel case ticks a resolutely modern self-winding 'Powermatic' movement (caliber C07.111) with an impressive 80 hours of power reserve. The dial is Silver. Both the case as well as the bracelet are partially PVD-coated in rose gold.
