The Big Date Gets A Makeover: Certina DS-1 In Black And Gold

Certina brings a refined take on daily versatility with the latest additions to its DS-1 Big Date collection, now available in two distinctive PVD-coated finishes. These models continue the evolution of the brand’s celebrated Double Security (DS) Concept, offering a blend of urban style and functional engineering.

Refined Case Design with Practical Dimensions

The new DS-1 Big Date references are housed in 41 mm stainless steel cases, now treated with matte black or gold PVD finishes for a modern aesthetic. The case thickness remains a slim 11.90 mm, enabling a comfortable fit under sleeves while preserving the robustness expected from Certina. Both versions maintain 100m water resistance, a testament to the DS heritage that began in 1959, when the brand first introduced enhanced shock and water protection in its mechanical watches.

Signature Big Date Display

At the heart of this model is the prominent Big Date complication, positioned at 6 o’clock. Unlike standard date windows, this display uses two independently-driven discs—one for tens and one for units—ensuring large, easily legible numerals. It’s a feature that emphasizes functionality without compromising the design symmetry of the dial.

Modern Colorways and Finishing Touches

The matte black PVD-coated version of the DS-1 Big Date features a sunray-brushed black dial complemented by silver-toned hands and sharply faceted dagger-like indices, which nod to classic Certina designs. The double date window is outlined in silver, with bold black numerals set against a contrasting white background for optimal visibility. This model is paired with a matching black metal bracelet, which combines matte-finished outer links and polished center links for subtle depth and contrast.

In contrast, the gold PVD model embraces a more traditional aesthetic. It is fitted with a midnight blue gradient dial that deepens in tone toward the edges, lending a rich visual effect. The gold-colored indices, hands, and framed big date window harmonize with the gold case, creating a cohesive and elegant look. A blue calfskin leather strap, secured with a folding clasp, completes the ensemble.

Engineered for Performance

Inside both versions of the DS-1 Big Date is the Swatch Group’s Powermatic 80 automatic movement, offering a generous 80-hour power reserve. Fitted with a Nivachron balance spring, the movement provides robust resistance to magnetism, temperature variation, and shock, further reinforcing the DS concept’s legacy of durability and reliability.

Pricing and Availability

The black PVD version of the DS-1 Big Date is priced at CHF 895, while the gold-toned model with the blue dial comes in at CHF 875. These latest additions to the DS-1 line successfully combine mechanical innovation with contemporary design, making them excellent choices for those seeking everyday watches with character, resilience, and clarity.
