With a diameter of just over 40 mm, the Nautic Star Quartz is a powerful piece of craftsmanship, without appearing overly chunky or pretentious. In addition to its size, which allows perfect readability both over and underwater, it has all the features of a classic divers' watch, including a screw-in crown and a fully threaded screw-down back, which guarantee high water resistance. All indices, points and hands are illuminated and the robust steel linked strap with its polished and satined elements has a safety catch as well as a diving extension. A particularly striking accent is set by the wide, uni-directional bezel made of high-quality ceramic. The watchcase is made from 316L stainless steel, the same category of steel that is used in surgical instruments. The glass is sapphire crystal so scratches do not stand a chance. And nestled in the centre, protected by a water resistance of up to around 100 metres, a Swiss quality Ronda movement keeps time.
