Chronoswiss Sirius Flying Grand Regulator Skeleton Limited Edition

Chronoswiss concentrates on the essentials for the new Flying Grand Regulator Skeleton: With its barely existent dial and a skeletonized movement, the stunning timepiece is thus freed from all superfluous material in an innovative manner. The result is a multidimensional Regulator watch with an elaborately constructed dial and deep insights.

The skeletonization exudes a particularly contemporary aura due to the masculine size of 44 mm and the innovative clear lines of the piece.

In addition to the uncomplicated language of design, the dynamic coloring with lots of black and red accents supports this effect. The funnel-shaped hour scale in dark cherry red is an absolute eye catcher. Even the inside of the strap made from distinctive hornback alligator captures your attention with the same color tone.

Chronoswiss’ love of detail and horological finesse is also on display in this latest addition to the Regulator collection: There is a smaller counterpart under the minute hand that accurately depicts an inverse image of the areas of the minute scale on a central miniature scale.

These are hidden from view due to the overlapping of the large scale with the hour funnel. This trick elicits unclouded joy for the sophisticated design because the minutes can still be precisely read.

The aesthetically skeletonized hand-wound movement is characterized by a stop seconds mechanism: Activating the crown triggers a slide that blocks the balance spring. Thus even the seconds hand can be stopped and precisely set.

Skeleton watches have become a tradition at Chronoswiss. For example, it was the first brand to present a serially produced, skeletonized automatic chronograph (Opus) in 1995.

This was followed with the Pathos model in 1998, also a skeleton chronograph with a split second function, as well as the first skeletonized chronograph in the sporty Timemaster line in 2014.

The Flying Grand Regulator Skeleton is limited edition only: 10 in red-gold case and 30 in stainless steel case.
