Chronoswiss Sirius Flying Regulator Watch

Chronoswiss Sirius Flying Regulator Watch Watch Releases

The regulator is one of the things that hails back to the start of watch making, alongside historical items like pocket watches. It’s nothing new that mechanical watches can be seen as something of an anachronism these days, but a big part of the reason they remain so successful is the “soul” that draws us in. There are other other types of movements (or devices, for that matter) that simply do a better job when it comes to accuracy and robustness, but for me, it’s the fascination of the tiny, purpose-built machine working away to give me information on demand. The regulator stands as a testament to watchmaking, and Chronoswiss has always made sure to keep true to the type, with their latest, the Chronoswiss Sirius Flying Regulator, refreshing the design.

Regulator watches are funny things. While they had their place mostly in the ateliers of days gone by, used for regulating the watches being worked on, the basic premise works well in a modern setting on your wrist. A large central minute hand gives you the minutes at a glance, while smaller dials for hours and seconds stand in the background until you actually need to know that information. That, of course, is the basic design we have with the Chronoswiss Sirius Flying Regulator, with the brand’s C.122 movement doing the heavy lifting. Chronoswiss has kept an eye on the regulator watch ever since their beginning, so how did they refresh this design?

Perhaps the case? Well, no, not here – the Chronoswiss Sirius Flying Regulator keeps the case to something that fits in with the rest of their lineup, with its coin-edge sides and onion crown. Perhaps the overall layout? Well, no the very concept of a regulator sort of dictates how things are positioned. That leaves us, then, with the dial itself. While we at times will point out smaller details that add dimensionality to a dial, the Chronoswiss Sirius Flying Regulator really does take things in a very three-dimensional direction. At the lowest level, you have a guilloche dial, which in and of itself gives some subtle dimensionality. Then, floated over that, which is where I am guessing the flying part of the name comes from, you have the rest of the dial.

In some ways, the upper deck of the Chronoswiss Sirius Flying Regulator is almost like a skeletonized dial, just with the ability to see more dial instead of a movement through the cutouts. The upper deck consists of the chapter ring, where the minutes are indicated, as well as the registers for the two sub-dials, which have the hours up top and seconds below. With the hands needing to be slightly above those surfaces and the minute hand needing to clear them all, one concern might be the overall height of the watch. Thankfully, that should not be an issue with the Chronoswiss Sirius Flying Regulator, as its overall case height is noted as being a mere 12mm. No, it will not win awards for thinness, but considering all the layers and the space needed for an automatic rotor, that height is no small feat.

In total, there will be six different variations of the Chronoswiss Sirius Flying Regulator released. At the top end of the range, there is an 18ct red gold case with either a silver or black dial, a DLC-coated steel case with a black or blue dial and the entry-level model in a steel case with blue or silver dial. At this point, only the base model in steel has an announced price, at 6,810 CHF. All of these are interesting options in their own right. While I cannot deny the appeal of a black dial paired with a red gold case, the winner here for me is the galvanic blue dial in the steel case. This just speaks to me of an everyday practicality, which really is what a regulator watch can, and should, be viewed as. The design may not be for everyone, but this is what I would consider an ambitious way to refresh a rather venerable style.

    I love me a nice regulator, and this offering does not disappointed. Like the deep blue and steel combo, as well as all the depth and texture in the dial. Regulators are nothing new to Chronosqiss, so it only makes sense that this is a well defined design.

  • Larry Holmack

    Very nice looking regulator!!! Love the blue dial!!! Only thing is…with my bad eyesight…I’d need a magnifying glass to read it…!!! Hummm…has anyone made a crystal that can magnify the whole dial????

    Actually…I gave my sister-in-law, who is a nurse, a Regulator for Christmas a few years ago. She wears it to work all the time!

  • Chaz

    Methinks Chronoswiss is a dying brand.

  • Love the watch, hate the regulator. Oh and that carbon strap looks about as right for this watch as an orange isofrane.

  • funNactive

    Unique time display – I like it. &, it’s the perfect case size @ 40mm.



  • PleaseSpellRoman4AsIV

    Love the blue dial. And so happy that nobody put a date window on this to ruin it.

    • pkansa

      Good call!

  • Ulysses31

    Great depth to the dial and a gorgeous lustrous blue face. I’m not usually impressed with Chronoswiss but they did almost everything right here.

  • ??????

    Probably the best Chronoswiss watch I have ever seen. Regulators are what they are really good at, and this piece has gorgeous patterns, perfectly balanced case and hands, – simply beatiful.


    for a regulator it is surprisingly easy to read even w roman numerals. the screws all over the dial are rather distracting and just add no visual value in my humble opinion.
    decent effort. case back pic would have been a bonus.

    • pkansa

      With the screws, I’m guessing that they realized they would have exposed infrastructure for the raised levels, and just decided to embrace it, rather than try to cover it up.

  • FrankD51

    Nice looking, but why the onion crown, that is so old fashioned now and really out of date. Put a nice, conventional ‘manly’ crown on it and it would be a real winner.

    • pkansa

      From what I’ve seen, the crown is one of those signature details for the brand.
