01 — OVERVIEW
An innovative, lightweight titanium flying tourbillon movement inside a two-piece quartz composite case.

Most watches are assembled from many parts. 01 SILICA's upper case is grown from a single block. The top bezel and the case middle are not two parts joined together — they're one seamless piece of watch-grade quartz composite, machined until every seam, every screw hole, every visible compromise disappears from the face and flanks. A separate caseback frame closes it from below, secured entirely by hidden titanium hardware — two pieces total, with nothing visible where they meet.

What's left holds a 5-gram titanium flying tourbillon, visible through two sapphires, double anti-reflective coated for perfect visibility of the mechanism — inside a case that weighs 23.02 grams25.02 with a featherweight 2-gram Dyneema strap on your wrist. This is a limited edition of 50 pieces. It exists to prove what the atelier can build, and to open the door to what comes next.

04 — ARCHITECTURE

Five decisions that
define the object.

01/05

Two-piece case, seamless top

The top bezel and case middle are machined as one continuous block — a single seamless surface across the face and flanks. A separate caseback frame closes it from below, secured by hidden titanium hardware.

Every case across the entire NR series — every model, every edition — comes from a single specialist manufacturer.

02/05

Hidden fixation

Every screw lives inside the case. Titanium capsules are bonded into blind wells and locked from the caseback, so the face and flanks stay untouched.

03/05

Flying tourbillon — 5-gram titanium

A custom flying tourbillon caliber, cut entirely from Grade 5 titanium at 5 grams — an ultra-thin 2.80mm movement (3.50mm including the 0.70mm flying tourbillon cage), visible from both sides through flat sapphire.

04/05

Clamping rehaut with floating columns

A skeletonized rehaut built from four sectors, each carrying its own index well, plus four further columns suspended separately on guide rails — locked in place with mirror-polished black anglage. The floating columns and the hands are cut from Aluminium-Lithium.

05/05

Super-LumiNova, embedded

The glow isn't painted on — it's poured directly into the case body and into the base of each hour well, so the light reads as part of the material, not an applied layer.

05 — EDITIONS

One neutral body.
Glow, crown, lume. The first editions.

The opening editions of the 50-piece run. Every edition shares the same neutral grey quartz composite body and speaks through three cosmetic accents, not case construction: the tinted rehaut, the crown, and the lume at the base of the hour wells. Further editions will be revealed, one at a time.

Every case shown below — across every edition — comes from the same single case manufacturer as the entire NR series.

Grey / White
Grey quartz composite case, grey rehaut, grey quartz-composite crown, white lume — internal glow and hand/index lume.
Grey / Blue Signature
Grey quartz composite case, blue-tinted rehaut, blue quartz-composite crown, blue lume — one accent carried through.
To be revealed
Further editions follow across the run of 50 — announced one at a time.

02 CARBON LIGHT

Innovative, lightweight titanium flying tourbillon — one-piece carbon monocoque case.

The record attempt. Built to be among the lightest tourbillons ever put on a wrist.

Where 01 SILICA proved the seams could disappear, 02 CARBON LIGHT removes what's left — one continuous carbon canister, no spring bars, no screws anywhere on the piece.

Target head weight: 11.00 g — engineered to be among the lightest flying tourbillons ever put on a wrist.

07 — INQUIRE

01 SILICA: an edition of fifty.
Considered one client at a time.

01 SILICA was built as a proof of concept — for what one atelier, working without compromise, can put on a wrist. Each of the 50 01 SILICA pieces, and every 02 CARBON LIGHT, is discussed individually, by appointment.
