ROMAN NELIUBIN ATELIER — NEXT CARBON LIGHT
A 5-gram titanium flying tourbillon by Le Cercle des Horlogers, cut into a single block of carbon. No case joints, no spring bars, no screws anywhere on the piece — built to be the lightest tourbillon ever put on a wrist.
NR-01 SILICA proved the seam could disappear. NR-02 CARBON LIGHT removes it entirely. Bezel, case middle, and caseback floor are cut from one continuous block of carbon composite — no horizontal joints, no internal fastening tubes, no lateral ears.
The strap threads straight through milled slits in the case wall. No spring bars, no screws, anywhere on the piece. What's left is a case built around one goal: to carry a 5-gram titanium flying tourbillon as the lightest tourbillon ever put on a wrist.
Chasing the lightest
tourbillon on record.
Four decisions that
chase the record.
One-piece carbon monocoque
Not two parts like NR-01 SILICA — one. Bezel, case middle, and caseback floor are a single canister, machined from one block of carbon composite with walls down-gauged to 0.50–0.60mm wherever load allows.
Carbon composite canister machined by Composite Busch — the sole case manufacturer across the entire NR series, every model, every edition.
Loop-through Dyneema interface — 2g strap
The strap threads directly through precision-milled horizontal slits in the 12H and 6H case walls. No spring bars, no screws — full elimination of external strap hardware, at just 2.00 grams.
Al-Li clamping rehaut — 0.70g
A skeletonized Aluminium-Lithium rehaut with four floating triangular islands and mirror-polished black anglage locks the movement in place — down-gauged to 0.70g combined with the hands.
Rigid contact caliber mount
The 5-gram titanium movement drops in from the dial side and sits in direct contact with the carbon vault. Under shock, energy transfers instantly across rigid planes instead of flexing through soft mounts.
Ten pieces planned.
Built to be the lightest.
NR-02 CARBON LIGHT is in active development. Each of the 10 pieces is considered individually, one client at a time — reach out to follow the build or discuss a reservation.
