The acoustic instrument for mechanical watches

Hear the
health of your movement.

A professional timegrapher for the watch you already own. Horlogemeter listens to the escapement, turns sound into timing data, and helps you understand what your movement is telling you.

The reading

From a quiet tick
to a clear signal.

Horlogemeter isolates the high-frequency impulse of the escapement, then renders the result in the language of a professional timing machine.

A better diagnostic ritual

Three positions.
One honest picture.

Rate in one position can look healthy. Variation across positions tells the deeper story. Follow a guided capture across dial up, dial down, and crown positions to reveal poise, isochronism, and positional delta.

  1. 01Place Follow the illustrated placement guide.
  2. 02Listen Capture the escapement in each position.
  3. 03Compare Read the movement as a whole.

A second opinion, in plain language

Meet Maître Laurent.

Your readings meet your watch’s caliber data, service history, and the questions only an owner can answer. Maître Laurent turns that context into a considered diagnostic consultation.

Amplitude is healthy, but the positional delta suggests the movement would benefit from regulation before its next service.

What is the watch’s service history?
Last serviced around 2019. No known impact.
Understood. I’ll weigh that against the amplitude and positional readings.

The result

Leave with more
than a number.

Every completed reading becomes a saved Movement Condition Certificate, built to be understood at a glance and useful at the workbench.
