Kross Studio Introduce KS 05 with World’s First Central Flying Tourbillon

Kross Studio KS 05 Titaium Blue Aventurine

Kross Studio are, in many ways, an odd brand. If you list the names of some of their watches, such as the Death Star, Bobba Fett and Space Jam, they don’t exactly sound like the most prestigious watches around. However, then you take a look at them and realise that they’re incredibly intricate pieces of haute horology worth taking seriously. And with the launch of the new Kross Studio KS 05 collection they’re taking themselves seriously as well with their first ever non-collaborative solo-branded watch – a watch that also happens to be the world’s first ever central flying tourbillon.

Kross Studio KS 05 Titanium

Considering that tourbillons are one of the most ubiquitous complications in haute horology it shouldn’t come as a surprise that the technology is constantly being developed and improved. The KS 05 pushes things forwards by combining two well established concepts into a single timepiece. Specifically, it combines a flying  tourbillon (a tourbillon suspended from below so that it looks like it’s flying) with a central tourbillon (a tourbillon mounted in the middle of the dial). As a quick note on terminology, Kross Studio refer to their piece as a “floating” tourbillon, which is exactly the same as “flying” and flying is the more common term.

Separately both these types of tourbillon add an extra degree of difficulty to their production and together those difficulties are multiplied. On an engineering level, a central tourbillon requires you to completely restructure the timekeeping elements of a movement so that the hour and minute hands become orbital. At the same time, by making the central tourbillon flying, the orbital mechanism can’t be supported by the mid-portion of the display. Fortunately, Kross Studio have pulled it off by developing a new movement.

The movement is the KS 7’005, a manual-wind piece with 220 components and a frequency of 21,600 vph. However, the most impressive statistic is that it has a 120-hour power reserve, which is rare for a tourbillon of any flavour let alone a brand-new type. They’ve achieved this by having a particularly large barrel – its diameter is larger than the radius of the watch – mounted centrally below the tourbillon. Plus, by having an ultra-lightweight tourbillon cage made from titanium it drains less power.

Kross Studio KS 05 Caseback

As for the structure of the watch as a whole, it has a 45mm case made from either titanium or 18k red gold depending on the version you opt for. It’s a crownless design that can be adjusted and wound via the D-ring set into the caseback. As an additional customisation option, the flanks of both the gold and titanium editions can be dressed in diamonds. But that’s not all because there are also multiple dials available as well.

On a technical level, the dial is split into three sections, the outer portion with time indication, the middle portion connected to the orbital hands and the inner portion below the tourbillon. The standard edition features aventurine glass in either blue or black, making the tourbillon appear to fly through a star-filled void. There’re then the precious stone versions with turquoise, jade or obsidian – although so far only the turquoise edition has been revealed and it’s my favourite.

This feels like a landmark moment for Kross Studio. This is the first time they’ve released a watch without any marketing spin from one of their many collaborators and they’re actually presenting it to the watch world on its merit as a piece of horology alone. The KS 05’s price definitely reflects the haute horology aspect of the piece as it’s CHF 88,000 – CHF 153,000 (approx. £78,000 – £136,000) depending on the case material, diamond embellishment and dial.
