DS-1 Big Date Powermatic 80 PVD / Black / Bracelet

The Certina DS-1 Big Date C029.426.33.051.00 debuted in 2025 as part of the expanded DS-1 collection, celebrating the 60th anniversary of Certina’s Double Security (DS) System. This version stands out with a bold urban aesthetic, pairing a 41mm 316L stainless steel case fully PVD-coated in matt black with a matching black PVD-coated stainless steel bracelet. The bracelet plays with subtle contrasts through alternating matt and polished surfaces, adding depth to the monochrome look. Its sunray-brushed black dial keeps the design sleek and modern, while the signature big date complication at 6 o’clock uses two separate discs for clear readability — an iconic detail of the DS-1 Big Date line. The watch is powered by the Swiss-made automatic caliber C07.651, offering an extended power reserve of up to 80 hours and equipped with a Nivachron balance spring for increased resistance to magnetic fields and temperature variations. A curved sapphire crystal with anti-reflective treatment protects the dial, while a transparent sapphire crystal case back reveals the movement. The DS-1 Big Date is water resistant to 100 meters thanks to Certina’s robust DS concept, combining refined urban design with enduring strength and precision — perfect for those who navigate the modern cityscape with confidence.
