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.

Special Characteristics

    Limited to 500 pieces
    Dark blue dial, with sunburst decoration

    Bezel with logarithmic scale and slide rule function
    Column wheel chronograph, exquisitely decorated
    Hybrid ceramic luminous elements, attached by hand
    Crystal and transparent case back made of sapphire crystal
    Water-resistant and pressure-resistant to 20 bar

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.

Sinn – 103 St Sa Ty Hd H Chronograph Special Edition

 

Sinn Spezialuhren – Instrument 103 St Sa Ty Hd H Classic hand-wound Pilot Chronograph Special Edition - 2025

Sinn presents the 103 St Sa Ty Hd H:  
Exclusive Special Edition for the watch magazine ARMBANDUHREN.

Click, to see the large size. ▶ BIG FOTO   

Instrumental watches, and in particular pilot chronographs such as the iconic models of the 103 series, have been a defining part of Sinn Spezialuhren’s collection since the mid-1960s. The classic case design, with its uncompromising focus on functionality and legibility, has fascinated watch enthusiasts for decades.

Click, to see the large size. ▶ BIG FOTO  

From the very beginning until today, we have developed numerous technologies for our high-quality timepieces, always closely followed by the specialist magazine ARMBANDUHREN. Out of this long-standing and successful partnership, an extraordinary watch has now emerged: the special edition 103 St Sa Ty Hd H.

Click, to see the large size. ▶ BIG FOTO  

Equipped with a traditional hand-wound movement and scratch-resistant sapphire crystal on both sides, it unites historical values with state-of-the-art watchmaking. A particularly striking feature: thanks to the sapphire crystal case back, the intricate mechanics of the hand-wound movement—without a rotor—can be admired in every detail, offering true pleasure to any connoisseur of traditional watchmaking.

Click, to see the large size. ▶ BIG FOTO  

The light blue glossy dial with dark blue, satinized subdials follows the classic tricompax layout. The result is a harmonious design that perfectly combines elegance and functionality.

Orange hands for the chronograph seconds, minutes and hours provide striking accents, while the white-orange alternating markings on the first ten minutes of the chronograph scale ensure optimal legibility.

Click, to see the large size. ▶ BIG FOTO  

A special refinement lies in the indices attached by hand as well as the hour and minute hands featuring hybrid ceramic luminous elements. By directly integrating the luminous pigments into the components themselves, an exceptionally high concentration of luminescent material is achieved. This results in extreme light intensity and perfect readability - even in complete darkness.

Click, to see the large size. ▶ BIG FOTO 

 This creates an intriguing contrast between the classic base model with its traditional hand-wound movement on the one hand, and the use of state-of-the-art technology on the other, underscoring the timeless design of the 103 series.

Click, to see the large size. ▶ BIG FOTO  

For enthusiasts of traditional measurements, the tachymeter scale on the inner bezel adds an extra dimension: allowing precise, manual calculation of speeds ranging from 60 km/h to 600 km/h. With low pressure resistance and water resistance up to 20 bar, the 103 St Sa Ty Hd H is a dependable companion when it comes to precision and reliability.

Each piece is delivered in an exclusive fine case with both a blue textile strap and a leather strap. With only 250 examples produced, this special edition ranks among the most coveted collector’s pieces within this illustrious model series.

The true SINN DNA is revealed inside the watch. Its high-end technological features offer maximum resistance and uncompromising functionality. Equipped with Magnetic Field Protection, Temperature Resistance Technology, and Ar-Dehumidifying Technology, the EZM 3 S delivers an impressive package of performance.
