SINN 903 St II B E

Product number: 903.091

The 903 series is presented in a version that has been technically completely redesigned. Visually recognisable, the navigation chronograph 903 St II B E is available as a standard model with a dark blue dial and has been elevated to an unparalleled technical level. The functionally designed dial imprints the navigation chronograph in our product range with decades of tradition. For example, the slide rule bezel with logarithmic scale can be used to calculate times, distances or fuel consumption. Of particular note is the use of hybrid ceramic luminous elements in the indices, which are meticulously attached by hand, the number 12 and the hour and minute hands. By integrating the illuminating pigments into the respective hybrid ceramic moulded part, a high concentration of illuminant is achieved, resulting in extreme light intensity and perfect readability in the dark.

However, the redesign of the case of the 903 St II B E in particular once again demonstrates our company's high level of innovation. This case features a silver-electroplated rotating bezel on the which can be smoothly operated from the outer diameter of the watch. The impressive waterproofness of 20 bar testifies to a feat of engineering that has long shaped the SINN brand.

The Tri-Compax arrangement of the silver-electroplated counters completes the classic navigation chronograph's design. The crowning glory of this model is its column wheel chronograph movement, which has a power reserve of at least 60 hours when fully wound. Watch connoisseurs will immediately recognise that the SINN logo as an appliqué is another fine detail of a consistently sophisticated watch.
