Certina DS-1 Big Date Powermatic 80 Watch - C029.426.11.051.00

Certina DS-1 Big Date Powermatic 80 – C029.426.11.051.00

The Certina DS-1 Big Date Powermatic 80 is the perfect fusion of mechanical innovation and classic design. Created for men who value Swiss precision and discreet refinement, this model expresses Certina's entire watchmaking tradition with a contemporary touch.

The highlight of this watch is its large date indicator (Big Date) at 6 o'clock, which offers superior legibility and sophisticated visual appeal. Inside, the Powermatic 80.651 movement beats, an automatic calibre that provides an 80-hour power reserve and a Nivachron™ hairspring, resistant to magnetic fields and temperature variations — synonymous with lasting precision.

The 41 mm 316L stainless steel case combines robustness and elegance, protected by a sapphire crystal with anti-reflective coating. The deep black dial with a radial brushed finish and applied hands enhances the sophistication of this model. The solid steel bracelet with a safety clasp completes the refined and comfortable look.

The DS-1 Big Date reflects Certina's Double Security (DS) concept — a construction system that guarantees superior resistance to water, impacts, and climatic variations.
