Press Release: Sinn 556 Anniversary.

In 2016, Sinn Spezialuhren is celebrating its 55-year anniversary - and the 556 Anniversary, limitied to 1,000 pieces, marks this special ocassion. With its satinised stainless-steel case and anthracite electroplated dial with sunburst decoration, the 556 Anniversary is an elegant watch for stylish occasions. While the limited of 1,000 pieces is documented by an engraving on the rotor, the dial features a direct reference to the anniversary by displaying the years ‘1961 - 2016’. Thanks to the transparent sapphire crystal back, the rotor engraving and the delicate mechanical movement can be seen particularly well. Additional features of this watch are its striking lines, minimal dial design and clear readability. The 556 Anniversary is resistant to low pressure and can withstand pressures of up to 20 bar.
