Jacob & Co. have resorted to aesthetic kinetics with their brand new Astronomia Régulateur watch. Looking magnificent with a 43mm cobalt blue sapphire glass and 18-karat rose gold case, the timepiece seamlessly blends the brand’s Astronomia heritage of ‘floating’ movement and 3D architecture with the concept of regulator watches. Inbuilt with an entirely new calibre JCAM56, the 250-piece limited run Jacob & Co Astronomia Régulateur is touted as the world’s first watch to feature a vertical rotating movement that completes one full rotation in 60 seconds/one minute.

The Three-Armed Astronomia Régulateur

A regulator watch is where the three timekeeping elements—hours, minutes, and seconds—are non-coaxial; they display time from different points on the dial and have separate hands to indicate their role in telling time. The Jacob & Co Astronomia Régulateur illustrates this trait with three arms completing 60 seconds/one-minute rotations. Following the Jacob & Co Astronomia signature of gravity-defying tourbillons, one arm of the new Régulateur is the solitary double-axis flying tourbillon at the 12 o’clock hour marker. The other two arms are the ‘floating’ sub-dials with Arabic markers; the minutes sub-dial at three o’clock sits, and the hour sub-dial at nine o’clock. Each of the arms/sub-dials also complete one-minute rotations. It’s the ring-shaped seconds scale with Arabic markers is the dial’s distinct quirk, occupying the usual spot of the minutes’ chapter ring. A slender 5N red gold dauphine hand sits intact, pointing to the seconds as the scale rotates counterclockwise within 60 seconds.

The Patented Jacob & Co Vertical Rotating Movement

The Astronomia Régulateur dial casts a royal appearance with the classic blue-meets-gold combination; blue sapphire glass forms the dial base with rose gold serving as the dial highlights through timekeeping markers, 5N red gold dauphine hands, tourbillon framework, brand logo, and ‘Swiss made’ quality stamp. A large, domed, blue and translucent ring forms the seconds scale, and the two domed translucent blue sub-dials sit above it. Protecting these delicate timekeeping elements of the dial is a protective curved anti-reflective sapphire crystal. The case comes attached to openworked lugs that secure a blue alligator leather strap with rose gold deployment buckle to the wrist.
