Tristan Ledard · TL01 movement

Model 1 —

No crown on the side: the crown on the caseback winds the movement and sets the time.

A watch drawn around its movement, and a movement drawn for it.

TL-Watchmaking Model 1 watch, blue dial and small seconds

The dial

A deep blue, the minute track and the hands in gold-inlaid steel.

  • Applied gold markers, doubled at twelve, and a beaded minute track
  • A steel plate engraved with the signature, screwed on at twelve
  • Small seconds at six, its ring laid over the flange
  • Steel hands, the hour hand ending in a gold square
Model 1 sapphire caseback: the gilt TL01 movement and the winding and setting wheel

The caseback

The movement, through the sapphire.

The glass follows the crown. Through it, the TL01 as it was drawn: the gilt bridges, the jewels in their settings, and the beating balance.

Turn the watch over, above, to see it beat.

The movement

The TL01, in hand.

This is where the prototype stands: the bridges, plates and wheels are made. A few changes are still needed, but the final movement should see the light of day in 2027.

The making

The TL01, from a block of brass to the bridges.

A block of brass on the milling machine, and a few hours later the TL01 bridges. Then the first wheels, and the lathe for everything that turns.

The TL01, part by part

A movement is built in an order.

  1. 01The main plate, drilled and gilt.
  2. 02The barrel and the train: the power, then its road to the escapement.
  3. 03The bridges, set down and screwed on their feet.
  4. 04The winding wheels: ratchet and crown.
  5. 05The balance and its hairspring. The watch starts to beat.

The workshop's own 3D model, as drawn in Fusion 360. Give it a turn.

The parts opposite are cut from the movement's own render, not redrawn.
