Corum presents a concept watch made from recycled titanium that frames a flying tourbillon and an aventurine stone dial set, quite unusually, beneath the movement.

The technical showcase, which Corum will produce in ‘extremely limited quantities,’ abounds in organic shapes with its rounded openings and gently curved case edges. Its movement appears to float amid sapphire bridges, which expose the aventurine dial below as well as all the movement’s gearing.

Corum powers the watch with a finely wrought flying tourbillon movement beating at 3 Hz (21,600 vph) offering a superior ninety-hour power reserve. The rare vertical gear alignment for the manually wound flying tourbillon here somewhat echoes the layout of the Corum Golden Bridge collection, one of the watchmaker’s best-known designs.

Corum also provides an eye-catch caseback design that again highlights the unusual gear layout. Corum designers have etched pop-art descriptions of the movement’s components adjacent to the caseback opening. 

The window whimsically highlights the tourbillon, mainspring and gear train with brief descriptions of the primary functions of each component.

The new watch only measures 39.5mm in diameter, which is unusually small for a complicated Swiss-made concept watch. Corum notes that the moderate size opens up the field of customers for the piece, which will fit on any size wrist. 

The bracelet here echoes the case and is crafted from recycled textiles and can be additionally adjusted using Corum’s own specialized bracelet adjustment system.

Price: $465,000.
