Introducing the Certina DS-1 Chrono Auto C029.462.26.051.00, a timepiece that debuted in 2026, boasting a robust 42.00 mm case crafted from 316L stainless steel. This watch features a striking two-tone look with a yellow gold PVD finish adorning the bezel, chronograph pushers, and crown. The case stands at a height of 14.32 mm and has a lug width of 21.00 mm. A sapphire crystal, treated with anti-reflective properties on one side, protects the dial, which is water-resistant up to 100 metres. This model showcases Certina's innovative DS Concept, which includes five key elements for enhanced durability: a sapphire crystal, an O-ring gasket on the stem, two O-ring gaskets in the crown, a dedicated gasket on the case back, and a strengthened case back. The black dial is designed with chronograph registers, while the Swiss-made automatic movement, calibre ETA Valjoux A05.231, operates with a silicon balance spring. This movement supports central hours, minutes, seconds, and chronograph functions. Completing the look, the watch is paired with a leather strap that features a quick-release system, secured by a stainless steel buckle crafted from 316L stainless steel.
