Motion is a prescribed illustration using documented frequency and specimen tooth counts. It is not a contact-force or rate simulation.

Reference geometry is loading.

A check for every part.

The inventory check is distinct from geometric certification.

View specifications and all 43 part checks

A passed inventory check confirms that a documented quantity has component roots and finite geometry. Exact profiles, tolerances, spring properties and physical contacts remain unverified.

Full source and assumptions record · Verification evidence

What we can verify.

The May 2025 technical communication establishes identities, quantities, assembly architecture and selected specifications. The 2020 manufacturer drawings add external interfaces. A published specimen supplies wheel counts. No complete factory CAD or component tolerance dataset was found in the public sources searched.

How the evidence is used

The 37.20 mm overall and 36.60 mm case-fitting diameters are different interfaces. Small seconds is 10.25 mm from the centre. Current reserve specifications take precedence over older documents; no reserve is predicted by this animation.

The 43 source rows include supplied assemblies and their children. This reconstruction allocates 49 selectable roots. That is not a manufacturer total of every elementary piece. Jewels, staff, roller, hairspring and barrel internals can belong to supplied groups; exact dimensions and adjustments remain unverified. Part handling is a simulator interaction, not a real servicing procedure.

All tooth curves, unspecified arbor coordinates, bridge depths, springs, clearances and fits remain reconstructed. The model cannot certify manufacturing interchangeability, force, friction, amplitude or watch accuracy.
