The Sinn 556 A demonstrates the company's eye for detail
The dial of the Sinn 556 A series is reduced to the absolute essentials. As a result, the timeless, minimalist design in matt black offers excellent readability. And thanks to the varied selection of bracelets -- including high quality alligator, cow, calf and horse leather, satin finished stainless steel and silicone – the model can easily be adapted to exactly suit your own tastes.
The 38.5 mm diameter stainless steel case is surmounted by a sapphire crystal with a non-reflective coating inside and out. Technology enthusiasts will also appreciate the exposed back, which houses the watch's beautifully complex mechanism under another robust glass covering.
All models in the Sinn 556 A series meet DIN 8310 technical requirements for water resistance. In addition, these premium chronographs also comply with the 8330 standard for aviator watches, meaning they're pressure-resistant up to an altitude of 12,000 metres. Unsurprisingly, the dedication to excellence displayed by the Sinn 556 A series – not to mention other pilot watches such as the 104 St Sa I – has garnered the company numerous awards.
Professional pilots, divers, athletes and scientists have all learned to trust in the reliability of Sinn watches. The brand's timepieces have been worn in space, in the Arctic ice and on stratospheric sky jumps, and in every case they've risen to the challenge. This shows the enormous robustness and stability of Sinn's specialist watches, and the Sinn 556 A collection shares the same tough DNA.
