- Mechanical-watch owners and movement enthusiasts
- Worth noticing
- For the ETA 6497 model, the notes say tooth counts are chosen so the fourth wheel turns once per minute, matching small seconds.
Field notes
The collection pairs each calibre with watch listings and technical specifications, while the principles section lays out how stored spring energy becomes motion at the hands. For the ETA 6497, the page identifies its part geometry as approximate and says its tooth counts are selected to produce the required one-minute rotation of the fourth wheel. The escapement is presented as a kinematic model rather than a physics simulation.
