Chronoswiss dresses its Delphis jumping hour watch with a stunning new ‘blue sapphire’ guilloché dial to create the Delphis Sapphire, a limited edition of fifty watches.
This latest version of one of the Lucerne-based watchmaker’s best-known models focuses the eye the watchmaker’s mastery of artisanal guilloche dials, while also reminding wearers that Chronoswiss has long been a premiere manufacturer of jump hour watches.
Chronoswiss places the larger blue dial underneath the prominent minute hand, with the seconds displayed at the 6 o’clock position within a swirling blue CVD-coated dial. The digital hour display dominates the top of the dial.
All this is placed within a 42mm by 14.5mm, seventeen-part knurled steel case, with the unmistakable Chronoswiss onion crown. Water resistance is to 100 meters.
The case protects the new automatic Chronoswiss manufacture caliber C.6004, developed in collaboration with the caliber makers at La Joux-Perret.
From the back you’ll see a skeletonized tungsten rotor, ruthenium-plated components and precise Côtes de Genève decoration.
Price: $16,700.
The watchmaker’s 3.3mm-thick A&S8320 caliber movement is one of the thinnest skeleton tourbillons around. Its thinness is enhanced thanks to its lack of an upper bridge, which means the tourbillon is of the ‘flying’ variety. (See additional specifications below). 
Skeletonized hands sit atop a bridge that straddles the visible gear train wheels. The open-worked approach continues with a see-through spring barrel at the top of the dial.
