Chronoswiss has added another star to its glittering Sirius collection with the dazzling unique Sirius Chronograph Moon Phase. The stunning timepiece with, a navy dial chronograph with a moon phase and analog date indicator, completes a trio along with the previous steel and gold white dial options from Swiss fine watchmaker.

 

Ensconced in a 41-mm steel case stylized with partially knurled edges, polished and brushed finishing, uncommon tipped chronograph pushers, and the characteristic large onion crown, this weighty customer comes with a Louisiana alligator strap using long, straight lugs. 

 

The blue, partially guilloché-decorated dial shows off an analog date window produced in a vintage style, with a red-tipped crescent moon indicator hand. Inside is a punctuated chronograph minute counter, with applied Breguet hour markers between the quarter hour positions. 

 

With plenty of classical design elements and vintage features that harken back to the first half of the twentieth century, which are nicely juxtaposed with modern finishing, the Sirius Chronograph Moon Phase can take its place among the Lucerne-based manufacture's iconic creations.
