Its design deliberately references the navigation chronograph created to mark the company’s 35th anniversary. The 903 Ti II Anniversary navigation chronograph adopts this established iconic appearance and combines it with technical further developments in terms of construction and materials.

This is already evident in the case, which is made of high-strength Grade 5 titanium. DSP Technology (see info box) allows the rotating bezel with an inner logarithmic scale to be operated directly by smooth rotation at its outer diameter of the watch.

That this timepiece achieves a water resistance of 20 bar with the aid of this technology underlines the exceptional engineering achievement behind the watch and bears witness to decades of experience in the development of sophisticated case constructions.

The appearance of the 903 Ti II Anniversary is clearly defined by its function-rich dial design. The bezel with logarithmic scale and slide rule function enables calculations relating to times, distances or currency conversions, for example.

An innovative approach extends right down to the details. For the hand-applied indices, the numeral 12 and the hour and minute hands, we use hybrid ceramic luminous elements.

By integrating the luminous pigments directly into the ceramic moulded component, an exceptionally high concentration of luminous material is achieved. The result is extreme luminous intensity and therefore perfect legibility, even in darkness.

The tricompax layout of the galvanically rhodium-plated sub-dials emphasises the classic character of the navigation chronograph, while the column-wheel chronograph movement ensures mechanical precision combined with proverbial reliability, supported by a power reserve of at least 60 hours.

Overall, the 903 Ti II Anniversary unites tradition and technology in an authentic manner – as a contemporary homage to 65 years of Sinn Spezialuhren, created for watch enthusiasts who regard functional versatility as a statement.

The SINN logo, applied as an appliqué, integrates perfectly into the high-quality overall appearance of the watch as a finely crafted, precisely executed element.
