A clean lock on the beat
Use the iPhone microphone or an external mic. Escapement listens for the mechanical beat and keeps the signal state visible.

Built for timing work
A tactile timing instrument for the pocket.
Escapement brings the discipline of a timegrapher into a calm, portable surface for watch owners, collectors, and repair benches.
Rate, beat error, amplitude, BPH
The core timing values stay present, legible, and close to the trace so every adjustment has context.
Each watch keeps its defaults
Profiles hold movement settings, thumbnails, and saved timing runs for repeatable checks over time.
Positions compared with restraint
Guided position reports turn separate readings into a clear timing picture without hiding the raw numbers.
Workflow
Listen. Lock. Measure.
Capture
Put a mic close to the movement and let the signal settle.
Analyze
Detect BPH automatically or set beat rate and lift angle by hand.
Report
Save runs, export traces, and compare positions when the watch needs more scrutiny.
Version 1.0
Designed for quiet, repeatable timing checks.
Start with a quiet surface, place the microphone close to the movement, and let the trace settle before saving the run.
