Sinn 103 Classic 12

A 600-piece limited classic chronograph with a ceramic bezel insert to mark the 60th anniversary.

The 103 is more closely connected to our company than just about any other series. After all, it was these timepieces that acquainted pilots, in particular, with the name Sinn Spezialuhren once the company was founded. The first model was developed in the mid-1960s, at that time equipped with acrylic glass and hand-wound movement. These watches can still be found in the range today, underlining their timeless design and huge popularity with many watch lovers. We’ve also continuously expanded the series, adding, for example, the latest SINN technologies and other features.

Classic in every sense of the word, this pilot chronograph is the perfect celebration of our company’s 60th anniversary – in the form of a special edition limited to 600 pieces. The 103 Classic 12 lives up to its reputation as a classic timepiece, but also boasts a modern interpretation, as demonstrated, for example, by the bezel insert made from ceramic – a material which appears for the first time on the 103 and is characterised by its outstanding hardness and the resulting exceptional scratch resistance. Another visual feature is the captive bezel itself, which features a twelve-hour scale to display a second time zone. The engraved numerals on the bezel are the colour of chamois, which is reflected in the three counters, all the printed elements and the luminous colour. The attached appliqués are rhodium-plated and luminous, as are the hour, minute and stopwatch second hands.

Even the place of origin of the watch is mentioned by name. The ‘Sinn Frankfurt am Main’ lettering thus adorns the glossy black dial with decorative sunburst to mark the anniversary. Both the crystal and the transparent back are made from high-quality sapphire crystal, enabling fascinating glimpses into the delicate work of the mechanical movement.

The 103 Classic 12 edition is waterproof and pressure-resistant up to 20 bar, resistant to low pressure and equipped with Ar‑Dehumidifying Technology for enhanced functional reliability and freedom from fogging.

To mark the special occasion, the edge of the glass back features the limited-edition number as well as the engravings ‘1961-2021’ and ‘60 Jahre’. The watch comes in a fine case with a dark green strap of wild boar leather and a cowhide strap with alligator embossing in black.

Additional Product Details

Sinn Watches was formed in 1961 by the legendary pilot and flight instructor Helmut Sinn. They began manufacturing flight watches based on his extensive aviation experience, this was primarily based on Mr. Sinn's dissatisfaction with the watches that were available for pilot and navigational purposes at that time. His own designs incorporated the features and functionality that he felt more fit for purpose as an instrument watch. This is a design philosophy that has transcended the company's culture right through to the present day. Sinn is now the world's most eminent manufacturer of high quality, precision, functional and purposeful instrument watches. From the beginning, their emphasis was on creating special purpose instruments that performed under extremely adverse operating conditions such as high speed, high and low pressures and altitudes, intense heat or pressure, extreme cold, high magnetic interference, and submergence in liquids. Sinn are becoming increasingly known for their instrument watches, and are today a force to be reckoned with as they lead the way in instrument watch design. The company changed hands in 1994 when Lothar Schmidt formerly of IWC assumed control and further expanded the boundaries of Sinn’s high tolerance manufacturing expertise. Over the past decade, Sinn has pioneered some innovative new technologies, including oil filled watch chambers to enable operation under extreme pressures, argon gas filled watches to prevent moisture infiltration, impact resistant gear suspensions, and new micro-lubricating techniques. Their timepieces are standard equipment in some of the most dangerous and adverse environments on earth - little surprise their watches are issued to the German military and elite forces. Above all the watches are manufactured and marketed to the world at large. Like the designs and their application areas, the pricing of the Sinn watches is most aggressive, making them available to most people. Due to distribution agreements Sinn watches can only be shipped to the UK and Ireland and certain countries where there is no Sinn agent assigned to that territory. Sinn watches are covered by a two or three year manufacturers warranty depending on the model.
