Black Steel DS-7 Chronograph Watch C0434173808100

The Watch

Certina is a Swiss manufacturer dedicated to crafting highly functional, expertly designed timepieces that showcase the brand's deep horological heritage. The DS-7 Collection draws inspiration from a 1970s reference, reimagined in a contemporary form that speaks to the brand's enduring expertise. The DS-7 Chronograph C0434173808100 features a round case crafted in black PVD-coated 316L stainless steel, elevated by a refined brushed finish that deepens its dark tone and adds a layer of sophistication. Perfectly proportioned for all wrist sizes, the case measures 41 mm in diameter and 12.15 mm thick, and is fitted with a fixed bezel bearing a tachymeter scale. It surrounds a flat anti-reflective sapphire crystal for optimal dial legibility and scratch resistance. On the right side, the DS-signed crown sits protected by case extensions. Its notched grip ensures secure hand and date setting. It is flanked by two pump-style pushers at 2 and 4 o'clock controlling the chronograph function. The whole assembly is sealed by a screw-down caseback featuring a beautifully engraved sea turtle in relief with a polished finish. The circular brushed border carries technical specifications, including a water resistance of 10 ATM.

The Dial

The dial on this watch is a modern classic with a relaxed, confident attitude. In black, it reads the time effortlessly while making a strong visual impression. A subtle sunray finish catches the light beautifully, intensifying across the three sub-dials at center. The outer ring features a slim minute railroad track paired with square indices. Opposite them, baton-style indices in silver are treated with Super-Luminova for exceptional legibility in low light - matched by baton hands for hours and minutes, also filled with the same luminescent treatment. They are joined by a slim silver chronograph seconds hand. The three counters display 1/10th of a second at 2 o'clock, the small seconds at 6 o'clock, and 30 minutes at 10 o'clock. The date window sits at 4 o'clock with a classic white background. The dial is completed by carefully placed text: the brand name at 12 o'clock, the collection name at 8 o'clock, and "Swiss Made" at 6 o'clock.

The Movement

This model is powered by a Swiss-made Precidrive™ quartz movement - specifically the ETA G10.212 caliber fitted with 4 jewels and powered by a 394 battery with a 38-month autonomy. It displays hours, minutes, small seconds, and date, along with a 1/10th-second, 30-minute chronograph function and an end-of-life indicator. This movement delivers an accuracy of +/- 10 seconds per year.

The Bracelet

This watch is finished with a sleek synthetic strap in black, elegantly accented with white stitching and secured by a deployant clasp crafted from black PVD-treated 316L stainless steel. Flexible and sporting in character, it measures 10 mm at the lug width and delivers all-day wrist comfort.

Water Resistance

This model offers a water resistance of 10 atmospheres, equivalent to 100 meters. Built to handle water with confidence, it's ready to join you in any aquatic adventure - from puddles to the pool. Showers, baths, and serious lap swimming? No problem. That said, our watch experts at Ocarat want you to know this model is not suited for diving (recreational or professional) and should be kept away from high-pressure cleaning equipment. We also recommend keeping the crown and pushers clear of water during immersion.
