The demand for a ladies' watch by Sinn, which grew increasingly frequent with the rising renown of the Sinn brand, was the basis for the concept behind our 456 series: robust, but not at all clunky. Distinctive, but not masculine. And above all, mechanical, but not heavy. The result is a sporty, elegant watch with all the characteristics typical of a Sinn timepiece. Its compact case has a diameter of only 28 mm but the same incisive design as the larger classic stainless steel models. The cleanly designed dials ensure superior readability under all conditions of use. The high-quality ETA 2671 automatic movement with 25 ruby bearing jewels and 28,800 alternations per hour forms the core of this dainty ladies' watch. In addition to the hour, minute and second, the date is displayed at the 6 o'clock position.
