Function truly meets form in this completely redesigned range of navigation chronographs
903 St B E II
The revamped stainless-steel case features a silver-electroplated slide-rule bezel with logarithmic scale that can be used to calculate times, distance or fuel consumption. It encircles a dark blue dial with silver-electroplated counters in a Tri-Compax arrangement.
Of note is the use of hybrid ceramic luminous elements in the hand-applied indices, the number ‘12’, and the hour and minute hands, which guarantees extreme brightness and perfect readability in the dark. The SINN logo as an appliqué completes the picture.
Another key feature is the column wheel chronograph movement, which has a power reserve of at least 60 hours when fully wound. It also boasts a water-resistance of 20 bar, which is a feat of engineering long distinguished SINN.
903 St HB
Limited to 500 pieces, this piece features the same silver-electroplated slide-rule bezel, Tri-Compax arrangement of the silver-electroplated counters, hybrid ceramic luminous elements, column wheel chronograph movement and water resistance of its 903 St B E II sibling. But what sets it apart is its glorious light-blue sunburst dial set within the stainless-steel case.
903 St II
Similarly, this variation, which is available as a standard model, is equipped with all the same features as its 903 St B E II and 903 St HB. Aesthetically speaking, however, its classic electroplated black dial with sunburst decoration against a stainless-steel case makes it the most conventional of the three.
