For 65 years, the name Sinn Spezialuhren has stood for technical excellence, functional strength, and the ambition to reinterpret proven designs. These very values are reflected in the 903 Ti II Anniversary model, limited to 500 pieces. Its design deliberately references the navigation chronograph created for the company's 35th anniversary. The 903 Ti II Anniversary Navigation Chronograph adopts this traditional, iconic appearance and combines it with technical advancements in both construction and materials.
This is evident in the case, which utilizes high-strength Grade 5 titanium. The DSP technology (see info box) allows the rotating bezel with its integrated slide rule function to be operated directly on the outer diameter. The fact that this technology enables the timepiece to achieve a water resistance of 20 bar underscores the extraordinary engineering behind this watch and testifies to decades of experience in developing sophisticated case designs.
The face of the 903 Ti II Anniversary is unmistakably defined by its feature-rich dial. The logarithmically scaled slide rule allows for calculations such as time, distance, and currency conversions.
Innovative design extends to the smallest details. The hand-applied indices, the numeral 12, and the hour and minute hands utilize hybrid ceramic luminescent elements. Integrating the luminescent pigments into the ceramic component creates an exceptionally high concentration of the luminous material. The result: extreme luminosity and thus perfect legibility, even in the dark.
The tricompax arrangement of the galvanically rhodium-plated counters emphasizes the classic character of the navigation chronograph, while the column-wheel chronograph movement ensures mechanical precision and proverbial reliability. This is further enhanced by a power reserve of at least 60 hours.
Overall, the 903 Ti II Anniversary authentically combines tradition and technology – a contemporary homage to 65 years of Sinn Spezialuhren, created for watch enthusiasts who understand functional versatility as a core value. The SINN logo, applied as a subtle, precisely crafted element, integrates perfectly into the watch's high-quality overall design.
