New: Sinn 103 Classic 12

Pinterest LinkedIn Tumblr +

Sinn releases a new 600-piece limited classic chronograph with a ceramic bezel insert to mark the 60th anniversary. Presenting the Sinn 103 Classic 12.

Press release information.


The Sinn 103 is perhaps the most classic of all Sinn’s creations. Made originally for pilots, this has been an icon of not only the maison, but also of the industry. The base is the existing Sinn 103, but with some changes. The most immediately recognizable is the use of a ceramic insert for the bezel, the first time it is used on the 103 series.

The movements used on the 103 have been variants of either the Valjoux 7750, the Concepto C99001, or the Sellita SW 510. And on this Classic 12, the movement chosen is the Sellita. Sinn choices of movements are based on availability and the palate from which they chose from are always the rugged, reliable, and trustworthy chronographs.

The 103 is more closely connected to Sinn 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.
