The 21st century places exceptional demands on our timepieces. High-end wristwatches today have to prove themselves in three ways at once: in style, resistance and precision. With its most recent edition of the popular DS Action Diver, Swiss watchmaker Certina has created a winner in all three areas. The 40.5-mm diver's watch scores high with its timelessly elegant design, water resistance to 300 metres, and a modern automatic movement with anti-magnetic balance spring.
