Chronoswiss Sirius Regulator Classic

As a new addition to the Chronoswiss Regulator family in 2016, the Sirius Regulator Classic stands out by its classic and timeless appearance in combination with fresh and sporty emphases.

Distinguished details such as the guilloched interior of the display for hours and seconds, the precisely aligned length of the hands and the thrilling contrast between matt-finished and polished surfaces create a harmonious overall appearance.

Not least with its carefully selected combinations of colours and materials Chronoswiss has created an unconventional automatic watch that masters the balancing act between watchmaker tradition and timeless design.

Sirius Regulator Classic CH-8723-SI: Stainless steel case, galvanic silver dial

The model with the 40 mm case made from stainless steel is available in three variants: in an entirely purist form with a dial in galvanic silver and thermally blued hands or, less conventional, in deep midnight blue, while the blue is echoed in both models by the interior of the calfskin strap.

The third variant is all classic and sporty: On the dial in galvanic black, signal red tones add that little dynamic extra that is emphasised by the casual rally design of the strap with red colour elements.
