Mechanical Sinn watches


Sinn 556 series watches will impress you with their clean lines and easy-to-read dials. Based in Frankfurt am Main, the German watch brand is known for its Main special professional watches. They are widely used by Federal Police units as well as in sports and athletics. With the 556 series, Sinn launches a watch that is primarily aimed at everyday use. Durable and resistant, a Sinn 556 watch will remain reliable in every situation.

The Sinn watch company is constantly developing innovative technologies such as its Ar dehumidifying technology, the lubricant-free DIAPAL lever escapement and HYDRO technology for mirror-free readability underwater. Perfect readability and durability, even under extreme conditions, are typical trademarks of special Sinn watches; this is reflected in versions of the 556 series. In the watch industry, Sinn stands for creative technical innovation and the leading German engineering brand enjoys international recognition and popularity.

Sinn 556 Series – Sinn 556a and Sinn 556I

Sporty and elegant, 556 watches always impress with their striking shape, reduced dial design and excellent readability. The 556 series, with its typical Sinn characteristics, is related to pilot’s instrument and navigation board clocks. Sinn Spezialuhren has launched two versions in its 556 series: the classic 556a and the 556I extension.

The Sinn 556 is a functional watch with a streamlined appearance. It’s the ideal companion to everyday life. The timepiece, made of satin finish stainless steel, keeps things minimal with only time and date display. Its elegant 38.5 mm case is equipped with a cover and transparent base made of anti-reflective sapphire crystal glass, allowing you to see right into the filigree mechanical movement. Glow-in-the-dark bar indices and central hands enhance the matt black dial.

In the 556a version, the date window is situated between 4 a.m. and 5 a.m. For the 556I model, the date window is at the 3 o'clock position. Inside the watch, the ETA 2824-2 automatic movement with a stop-second device and special shock resistance and anti-magnetism features keeps this stylish timepiece ticking. Additionally, these Sinn 556 series watches are water-resistant and resistant to negative pressure up to 200 metres. A desirable wristband selection leaves nothing to chance with straps made of either leather, silicone or solid stainless steel.
