Give
back time.

Before working on a piece,
listen to what holds it back.

Scroll down: into the caliber

01 / Opening

Enter without erasing
the traces.

Every mark reveals a relationship. Opening helps us understand it.

A · Power reserve · Barrel

The impulse begins held in reserve.

The barrel stores the energy that makes the whole journey possible. A coiled spring in no hurry.

B · Transmission · Gear train

Force learns a scale.

The gear train distributes motion before passing it to the pulse. Each jewel reduces friction.

C · Cadence · Balance and hairspring

Moving forward also means pausing.

Balance and hairspring alternate impulse and pause to produce a measure.

Nothing moves alone.

A watch builds time by transferring energy, reducing it and giving it cadence, across many parts.

02 / Mechanism · Complete chain · stable

The logic of
the invisible.

Remove a function. Follow the consequence.

Current reading

The pulse finds its rhythm.

The three layers form a continuous chain. Observation comes before any adjustment.

The CIRCA approach

Preservation also
means knowing pausing.

A mark of use is not necessarily a flaw. Restoration means distinguishing a piece's memory from what keeps it from working.

03 / The bench

Four gestures, no hurry.

  1. 01

    Take it apart, one part at a time

    Every screw goes to its own place in the tray. Nothing is improvised on the way back.

  2. 02

    Adjust the balance

    The hairspring is checked for flatness and centring. A tenth of a millimetre changes the day.

  3. 03

    Oil only what turns

    One drop per jewel, the size of a pinhead. More oil is not more care.

  4. 04

    Write it down

    Every measurement goes on the piece's card, so the next hand knows what we did.

04 / The test

The tape does not lie.

On the timegrapher every tick becomes a dot. A healthy piece draws a single, straight line.

Two lines drifting apart: the balance limps and the watch runs fast.

18,000 bph · 1 dot = 1 tick

Objects that hold time.

Fictional study pieces, without brands or historical attribution.

  1. Open silver pocket watch with its movement visible, on a dark workbench.

    Pocket watch

    Reserve and pulse. A manual caliber lets us trace energy from barrel to balance.

  2. Brass mechanical counter with its cover removed and its number drums visible.

    C.02

    Mechanical counter

    Transmission and return. Levers, springs and wheels turn a gesture into a count.

  3. Partially disassembled brass measuring instrument with a graduated dial.

    C.03

    Reference and repetition. A reading only makes sense against a reference.
