CARBON LIGHT
A 5-gram titanium flying tourbillon, cut into a single block of carbon. No case joints, no spring bars, no screws anywhere on the piece — built to be among the lightest tourbillons ever put on a wrist.
01 SILICA proved the seam could disappear. 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 one of the lightest tourbillons ever put on a wrist.
Chasing the lightest
tourbillon on record.
Case mass scaled from 01 SILICA's quartz composite case (4.20g) by density ratio (1.55g/cm³ carbon vs 1.98g/cm³ quartz composite) and thickness ratio (6.94mm vs 7.44mm). Crystal is PMMA plastic (~1.18g/cm³) at 0.70mm, following a flat-top, no-sapphire methodology for this piece. The movement sits in a dedicated carbon mounting frame seated on gaskets, seals throughout add 0.05g, and crown & stem are reasoned from titanium-core/carbon-ring cap geometry scaled to this case's 6.94mm thickness.
All figures on this page are current engineering targets, based on final CAD and confirmed material densities — not measurements from an assembled unit. Final production figures may shift slightly once the first pieces are built and weighed.
Four decisions that
chase the record.
One-piece carbon monocoque
Not two parts like 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.
Every case across the entire NR series — every model, every edition — comes from a single specialist manufacturer.
Loop-through Dyneema interface — 2-gram 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.
Clamping rehaut with floating columns — 0.70-gram
Same architecture as 01 SILICA — four sectors, each carrying its own index well, plus four further columns suspended separately on guide rails — but every non-structural section is thinned further here, down-gauged to 0.70 grams combined with the hands. The floating columns and the hands are cut from Aluminium-Lithium.
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.
A limited edition.
Built to be among the lightest.
