THE LIVING ENGINEERING WORKBENCH
WEAVE.
Take a watch apart, change one condition, and compare what happens.
My dad loves watches. This is how I’m learning to see what he sees in them—and how that curiosity shapes the software I build.
Preparing the open movement…
LOOK UNDER THE RESULT
Every change leaves a thread.
The reference uses the open OM10’s documented 3.5 Hz frequency and 18 mg·cm² balance inertia. This experiment adds an ideal torsional oscillator and couples its rate to the illustrated gear train.
Sources, equation & model limits
The implied reference stiffness is 8.7050e-7 N·m/rad, derived from the ideal equation Iθ″ + κθ = 0. It is not a measured spring specification. The graphical amplitude and layout are illustrative. The comparison excludes friction, escapement contact, temperature and wear, and does not predict a real watch’s accuracy.
Gold marks the selected connection. Cyan is the reference; coral is the alternative. Traveling points trace a relationship; they do not measure energy. Separation and section cuts change the display only.

The person behind the project
A note from Luis.
My dad’s love of watches connects my interest in physics and geometry to a practical software habit: change one condition, compare the result, and keep the evidence.
Who it helps
Curious people learning how a mechanism works, and engineers investigating how a system behaves.
Try this
Separate the watch, choose Split reality, and add 10% inertia. See 60 seconds, then match the rate. The software investigation applies comparison to retries and recorded trace files.
