Showing at WatchTime LA: Chronoswiss Sirius Chronograph Moon Phase

As part of Chronoswiss’ showing at the upcoming WatchTime Los Angeles event on May 3-4, the Swiss brand will be showcasing the new Sirius Chronograph Moon Phase. The watch, a navy dial chronograph with a moon phase and analog date indicator, joins the previous steel and gold white dial options from the independent Lucerne-based watchmaker.

The complicated new piece uses a 41-mm steel case stylized with partially knurled edges, polished and brushed finishing, uncommon tipped chronograph pushers, and a large onion crown. It stands somewhat tall on the wrist at 15 mm, and is secured with a Louisiana alligator strap using long, straight lugs. On the blue, partially guilloché-decorated dial is an outer analog date window produced in a vintage style, complete with the red-tipped crescent moon indicator hand sweeping over the face. Inside this element is a punctuated chronograph minute counter, with applied Breguet hour markers between the quarter hour positions. Then towards the top of the dial is the chronograph 30-minute counter, with running seconds at the 9 o’clock, 12-hour chronograph counter at the bottom, and a moon phase at the 3 o’clock accented with a 0 to 29.5 scale representing the length of a typical lunar cycle.

Lacquered white “Breguet Losange” steel hands sweep over the face, with a simple pointer used for the chronograph seconds, while white rain drop style hands are used for the chronograph sub-dials and a simple pointer is used for the running seconds. The moon phase is powered by the automatic Chronoswiss caliber C.755, which is based on the ETA 7750 and capable of a 46-hour power reserve. This movement is visible through a sapphire caseback and is finished using a skeletonized and rhodium-plated rotor with Côtes de Genève.


The watch throughout uses neo-classical design elements, borrowing vintage features from the first half of the twentieth century alongside modern finishing and production. These features are seen in the analog date indicator with its classic looking crescent moon, alongside the knurled edges of the case and onion crown channeling early converted pocket watches. The Breguet numerals, hands, and use of guilloché, alongside the pointed tips on the chronograph pushers, blue dial color, and rhodium plated movement offer further elements common in modern luxury watches, and work to elevate the watch among Chronoswiss’ and the larger market’s offerings.

While pricing for the watch is still unavailable, it will likely market similarly to the previous steel models (pictured above) in the series, around 7,950.00 CHF. To see the new watch, alongside many other exciting models by Chronoswiss and 26 other leading brands in the industry, be sure to get your ticket to the WatchTime LA fair coming up on May 3-4 at Hudson Loft in Downtown LA.
