Hautlence‘s Sphere Series 4 sets time in motion without a hint of theatrics. A sand-toned hour sphere turns on three axes inside a fully skeletonised stage, while retrograde minutes sweep and snap back. It is kinetic sculpture with a timetable.
The rectangular grade 5 titanium case is compact yet architectural, 37.0 x 45.0 x 17.4 mm, water resistant to 10 ATM, with sapphire crystals front and back. The olive green and sand palette softens the geometry, like stone caught in late light.
On the left, the star: a structured titanium sphere for the jumping hours, sandblasted and filled with white Super-LumiNova. It rotates through three axes via four bevel gears running on two crossed axes set at 21 degrees. The effect is hypnotic, but the mechanics stay legible.
Around it, the dial is air and bridges. Rhodium-plated, frosted brass forms the base, while a sapphire intermediate dial carries applied minute numerals in Globolight. The sphere appears to float, yet reading the hour is immediate.
On the right, a retrograde minute hand travels a 180-degree arc along a suspended track, then returns in a controlled instant. The snap is crisp, the motion purposeful, a neat reminder that energy is being stored and spent with intent.
Inside beats the hand-wound calibre A82, designed and assembled in-house, with a hairspring from sister firm Precision Engineering AG. It offers a minimum 72-hour reserve at 21’600 vph, built from 160 components with 31 jewels. A skeletonised barrel and ratchet show mainspring tension at a glance, while a safety system guards against improper setting.
Practicality is not forgotten. The watch is paired with an olive green suede strap and titanium folding clasp. Limited to 28 pieces, it wears its complexity lightly and its purpose plainly – to make time visible, not just measurable.
