903 St II G

One new colour world, one technical masterpiece: the navigation chronograph 903 St II G exemplifies the continued evolution of a highly functional model range. The distinction lies in the visual details. The 903 St II G with a green dial reveals an expressive sense of depth.

The character of the 903 St II G is defined by their function-rich dial design. Using the slide-rule bezel with logarithmic scale, calculations for determining time, distance, or currency conversions can be performed with precision. The indices attached by hand, the numeral 12, as well as the hour and minute hands are made of hybrid ceramic luminous elements, providing exceptional luminosity for perfect legibility in the dark.

The bezel, operated directly by sliding along its outer diameter, demonstrates a level of engineering precision that is second to none. That the watch achieves water resistance up to 20 bar thanks to DSP Technology underscores our decades of technical expertise.

The tricompax arrangement of the galvanically silver-plated subdials establishes these models as classic navigation chronographs. Inside, a column-wheel chronograph movement performs its task with absolute reliability, driven by a power reserve of at least 60 hours.

The 903 St II G thus strikingly demonstrates how functional excellence and technical sophistication merge into a clear, purposeful design. The SINN logo as an applied emblem once again bears witness to the brand’s attention to detail and its uncompromising commitment to design clarity.
