Mastering the Mechanical Watch
Like Duolingo, but for Mastering the Mechanical Watch. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
For the part of you with thirty open tabs that never became anything.

Key ideas in Mastering the Mechanical Watch
- Mechanical watches rely on potential energy stored in a coiled spring
- The mainspring acts as the 'power plant' for the entire movement
- Winding the crown physically tightens the internal metal ribbon
- A tighter coil stores more energy to be released later
- The watch stops when the spring reaches its natural, relaxed state
- The length and flexibility of the metal ribbon allow for significant energy storage
- Identify the source of energy in a mechanical watch
- The 'power reserve' is determined by how long the spring takes to uncoil
- The mainspring is housed in a component called a barrel to manage this tension
- The sequence of energy transfer when winding a watch
- The relationship between the mainspring's physical state and the watch's operation
- Understanding the role of the mainspring barrel in long-term energy storage
- Mechanical watches have a finite power reserve
- Without active winding, the stored tension eventually depletes
- Manual watches have a physical 'hard stop' when the mainspring is fully coiled
- Automatic watches use a sliding bridle (clutch) that slips against the barrel wall

Eight weeks. You meant to finish. You didn't.
Tomo gives Mastering the Mechanical Watch the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
Here's what playing it feels like
A real question from this course. Take your best guess.
If a mechanical watch has no battery or solar panel, what physical component holds the energy that keeps it ticking?
