01 — OVERVIEW
An innovative, lightweight titanium flying tourbillon movement inside a quartz composite case, seamless across the face and flanks.

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 piece of watch-grade quartz composite, seamless across the face and flanks. A separate quartz composite caseback frame carries the rear sapphire and closes the case from below — two parts in all.

Inside sits a 4.9-gram titanium flying tourbillon, visible through two sapphires, double anti-reflective coated for perfect visibility of the mechanism — in a watch that weighs 19.31 grams. 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.

03 — ARCHITECTURE

Four decisions that
define the object.

01/04

Seamless face and flanks — one block above, one frame below

The upper case — bezel and case middle — is machined from a single block of quartz composite, with no seam across the face or flanks. A separate quartz composite caseback frame carries the rear sapphire and closes the case from below. The two parts meet on the underside.

Every 01 SILICA case, in every edition, comes from a single specialist manufacturer.

02/04

Flying tourbillon — 4.9-gram titanium

A custom flying tourbillon caliber, cut entirely from Grade 5 titanium at 4.9 grams — ultra-thin, and visible from both sides through flat sapphire.

03/04

A rehaut unlike any other

The rehaut is an invention of its own — a construction unlike any other in what it is made of and how it carries the hours. We reveal it on our own terms.

04/04

Super-LumiNova — lit from within

One pigment, three sources — the hands, the hour scale, and a glow from inside the case itself. At night the object reads as one light, not a scatter of dots.

04 — EDITIONS

One architecture.
Its own chromatic signature.

The first edition of the 50-piece run. Each edition is defined by its own chromatic signature — the tinted rehaut, the crown centre and the colour of its glow. Further editions will be revealed, one at a time.

Every case, across every edition, comes from the same single specialist manufacturer.

Edition I
Grey quartz composite case. The signature reads in two places — a blue-tinted rehaut and the blue crown centre.

The second edition — announced on its own.

06 — INQUIRE

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

01 SILICA is conceived as a proof of concept — for what one atelier, working without compromise, can put on a wrist. Each of the 50 pieces is discussed individually, by appointment.
