Chronoswiss Sirius Flying Grand Regulator Skeleton Watch Watch Releases

Last year, Chronoswiss put out a new regulator watch called the Sirius Flying Regulator. The Chronoswiss Sirius Flying Regulator was special in the sense that its sub-dials for the hours and seconds seemed to be floating on the main dial - hence "Flying Regulator." For 2017, the brand is releasing a new skeletonized version called the Chronoswiss Sirius Flying Grand Regulator Skeleton that is going to be a limited edition. Let me talk you through this new watch now.

For anyone unfamiliar, regulator-style watches are those where the hours, minutes, and seconds are read off separate dials, usually with the minutes displayed prominently in the center. They are a bit of an oddity these days and something you don't see too often. But with a cool and technical-sounding name, in recent years more and more brands have been rediscovering this kind of watch as a way to stand out and another style option around which to build designs. Their historical origin adds to the appeal, and that is that this type of clock was used in watch manufactures against which the watchmakers would set the watches as they worked on them.

The Chronoswiss Sirius Flying Grand Regulator Skeleton watch comes in stainless steel and 18K red gold. And compared to the regular Sirius Flying Grand Regulator watch from last year, the case size has been enlarged by 4mm to 44mm. Water-resistant to 30m, it is also ever so slightly thicker at 12mm - as last year’s model was 11.8mm. The case design remains the same, with a polished bezel and knurled sides. There’s also a sizable onion crown. All in all, the case is very classic in its design and gives off a very antique vibe.

The key changes are on the dial. It is skeletonized and this gives its owners a very clear view of the inner workings of the movement within - more on the movement later. At 12 o’clock is the sub-dial for the hours, and at 6 o’clock is the sub-dial for the seconds. The two sub-dials have the same floating effect as last year’s model, which gives the dial a three-dimensional quality.

Both sub-dials have a unique funnel shape, but it is more apparent on the hours sub-dial, with translucent red varnish and white Roman numerals. In red, it stands out on the dial, aiding legibility so you know which dial is more important to read at a glance. Also interesting is the small inverse minute scale under the central minute hand in the very center of the dial, as this allows the minutes to be easily read regardless of any subdial cutting off the minute track. The hour and minute hands are rhodium-plated and diamond cut, while the seconds hand has been given a red lacquer to provide it with some contrast.

The movement within is the Chronoswiss Caliber C. 677, which is based on the Unitas 6498. It has been extensively modified and finished to include a hand-crafted Glucydur balance with hacking function, Swan-neck regulator, polished screws and plates, and skeletonized gear wheels. In fact, looking at the photo above, it doesn't look like a Unitas 6498 at all. With a 40-hour power reserve, the Caliber C. 677 beats at a leisurely 18,000vph, or 2.5Hz.

From the press photos, the Chronoswiss Sirius Flying Grand Regulator Skeleton watch looks pretty handsome, and I quite like the case design, especially the knurled sides and onion crown. But I’ll reserve my final judgment until I see it in person (or at least hands-on photos of the watch). That said, the thing about regulator-style watches is that, for the most part, they are the kind of watch you either love or hate because the way they display time is not to everyone’s liking and certainly takes some getting used to. The Chronoswiss Sirius Flying Grand Regulator Skeleton is limited to 30 pieces in stainless steel and 10 pieces in 18K red gold. It is priced at €8,960 and €19,140, respectively. chronoswiss.com

    Every day I hope that open and skeletonised dials will become unfashionable, and every day yet more arrive. The odd thing is I never see anyone wearing one of these over-cogged watches, yet the tsunami fails to abate. So who’s buying them?

  • BrJean

    I really like this watch! There is a number of design elements which I appreciate: straight lugs; onion-shaped crown; decoration of gears; color accents. Dial legibility is pretty fine for a skeletonized watch. And last but not least the reasonable price.

    • Shawn Lavigne

      agreed.

  • Marius

    In my opinion, Chronoswiss is a very interesting brand that is usually underrated and overlooked.

    What I like about Chronoswiss is that this brand has a very unique and unmistakable design language coupled with technically interesting movements. Instead of simply taking design elements from other brands, Chronoswiss has a very unique, if a bit quirky aesthetic approach. Moreover, the movements might be Unitas and ETA, but they are so heavily modified that it’s hard to recognize their origin. This is a brand that really adds value to their timepieces, instead of just slapping a stock-standard ETA in a derivative case and charging $6,000 for it. Chronoswiss should certainly serve as an example for Bremont.

    My only problem is that these watches are quite expensive. €8,900 is a hefty price, but one has to keep in mind that we are talking about a skeletonized regulator. Besides the fact that this complication is interesting as well as quite rare, most regulators on the market today command much higher prices, so overall, Chronoswiss offers a decent value proposition.

    Ok,……….enough already !……Skeletonisation was fun for a while but i think it’s run it’s course and to be quite often cheapens the whole look. A nice open back is enough if you have something worthwhile to look at ( in this instance i don’t like the movement at all, it’s a bit clumpy. Looks like it was made with meccano ). A wee peek -a-boo window for a nice balance wheel or tourbillon. This kind of dial just annoys me , what am i looking at !, i just want the time gawd dam it !!!. I do like a nice onion crown but this is to big for the dial and being a leftie that would just annoy me digging into my wrist.It’s not boring so it escaped the bin…………………that is all.

    I don’t dislike chronoswiss, but I’m not too keen on this one. I’m generally not a fan of skeletonised watches to begin with, although I’m not without exception. That said, the key to a good skeletonised watch is the movement finishing, and this one has a problem in that regard. The ‘dial’ side main bridges are spartan and honestly just look like stamped metal.little to no anglage or high end polishing techniques. The movement view is nicer, with the black rhodium finishes and more to look at, and you can see some anglage: in the holes cut from the gears. In fact, the only place you’ll find it is on the inside of a circular hole, meaning this is all machine finished with no real hand work done. Those holes will have been ‘countersunk’ to get that angle effect, but there was no interest in the more painstaking but highly appreciated chamfering work for the bridges, giving a strange clash to the overall appearance here.

    I’ve always appreciated the Chronoswiss watches and find them among the best value proposition among the Swiss, together with Louis Erard, Alpina, Dubey & Schaldenbrand and Frederique Constant. However, I very rarely find skeleton watches attractive, and, unfortunately, this one isn’t an exepcion. I think that its so hard to create the harmony of all the inner parts, to make them look attractive, – that this task is near impossible in the entry-mid levels below 10k.

    cripes, the crown is roughly the size of a grapefruit I had this morning

    • IG

      Wow you got some tiny grapefruits, you haven’t sued the seller yet as a scumbag lawyer should?

      • Yojimbo

        what do you do for a living? I have four recent thank you cards on my desk.

        • IG

          I hate lawyers and proud of it.™

          • Yojimbo

            yeah you’re really blazing new ground there chief

          • Raymond Wilkie

            You can’t just trademark a sentence.It’s a bit of a sweeping statement is it not ?

  • Jerdp01

    All of the skeleton haters on this site are trying to justify their boring, overpriced Rolex purchase. Skeleton watches demonstrate the ultimate appreciation for mechanical movements. If you don’t like showing off the movement, then what’s the point of this esoteric hobby. You might as well buy a quartz, they keep better time.

  • Mr. Snrub

    I’m not against skeleton watches but this feels overdone. The open sub dials and big exhibition caseback would have been sufficiently interesting.

    The disco onion has charm but given its size and that I wear my watches low on the wrist it might prove uncomfortable.

  • Sevenmack

    The problem isn’t the skeletonization. It is actually nicely done. The problem is the effort to make the watch legible has given the Chronoswiss something out of the Stuhrling Original bargain bin. The designers could have made better choices such as just going all Movado and ditching the minute markers.

  • Yan Fin

    I like the non-profit skeleton version much better.

  • Lincolnshire Poacher

    I think these watches are okay. I like the Breguet style cases, and onion carbuncle.
    Skeleton dials have a whole issue with legibility, which is added to here with the regulator layout.
    The view of that lovely big balance wheel, through the back display window, is a treat. I’m not convinced by the bright red/crimson on the dial. I think it might have looked softer, with a more neutral colour.

  • Ulysses31

    It’s not bad. Legibility is OK, not brilliant, and I appreciate the dash of colour from the sub-dial. It gives the eyes something to focus on.
