Certina Watch DS-7 Chronograph Titanium C043.417.44.041.00. Just as sporty, if not more so, the new DS-7 Chronograph is fitted with a Precidrive quartz movement in a round, 41 mm stainless steel case. Complementing the hour, minute, small seconds and date displays are a central stop seconds, 1/10th second display and a 30-minute counter. A tachometric scale on the slim bezel offers an easy way to measure speeds. With a metallic shine or totally cool in brushed black – these watches are contemporary classics you’ll want to wear every day.
