| It's a mechanical movement regulated by quartz. In a

| balance wheel. In a Spring Drive movement, the escapement
| is replaced with an electromagnetic "brake" governed by a
| quartz crystal. So it still has many of the
| characteristics of a mechanical watch: it's still powered
| entirely by a main spring which can be wound or
| automatically wound by your body movements, it needs
| regular maintenance like other mechanical watches, and it
| isn't as durable as most quartz-only watches.

| My project at the moment is to try to make a mechanical watch.
|
| The concept is that it will only have one hand (the hour hand),
| and the mainspring barrel will encircle the entire movement,
| you'll wind it up by rotating the bezel (and therefore the outer
| part of the barrel) clockwise, and the mainspring will drive the
| inner barrel clockwise. The hour hand is mounted directly on the
| inner barrel (which therefore completes 1 revolution per 12
| hours), and the rest of the movement only exists to regulate the
| speed at which the inner barrel rotates. So the rest of the
| movement will be a series of gearings-down, with an escapement at
| the end.
|
| And to set the time, the movement will be mounted into the case
| with a ratchet, such that when you turn the bezel _anticlockwise_
| , the entire movement (and therefore the hand) rotates
| anticlockwise allowing you to set the hand. You'll only be able
| to set it as precisely as the ratchet (i.e. you'd need 720
| positions of the ratchet to set it to 1-minute precision), but
| the watch will never keep particularly good time anyway so I
| don't think this is a problem.
|
| Yesterday I got an escapement at almost-watch-scale ticking for
| the first time, albeit erratically and requiring enormous drive
| torque: https://www.youtube.com/watch?v=xvNODOp6uBc (3d printed
| for expediency, the real one will all be machined; and I say
| "almost-watch-scale" because although it fits inside the 50mm
| diameter that I am aiming for, it is obviously too thick to go

| Looking at drawings 3 & 4, these linear vs rotational springs are
| analogous considering they are each at rest in the center of the
| user control slider. They can act like a spring in either
| direction, and are basically sitting there in the neutral or non-
| energy-storing condition (zero-sprung or zero-wound respectively)
| until you move the slider away from the center position.
|
| Take a look at the 9th or 10th interactive drawing, where you can
| move the slider to the right to wind the mainspring, then release
| the slider to watch the mainspring unwind.
|
| When the energy is depleted, all the bands in the coil are
| bunched up around the outside of the barrel. It's not much of a
| spring any more.
|
| This is the same type of torsion spring as in drawing 4 but with
| the mainspring being used for primary energy storage there is no
| desire for recovery to a neutral position from both clockwise &
| counterclockwise directions like you see in drawing 4. Instead
| you only need to ever draw energy from storage to use in a single
| rotational direction. Opposite rotation is used only to store
| externally applied energy.
|
| So you wind it in one direction to store energy then it releases
| the energy in the opposite direction.
|
| But without the precurvature shown in drawing 11 the torsion
| spring would tend to be exhausted when it was "zero-wound" like
| the one in drawing 4, with the coils widely spaced away from each
| other, free to absorb & recover energy from either rotational
| direction. And since we only need to draw energy in one
| rotational direction, that amounts to only half of the energy the
| spring is capable of storing for our purposes. Notice how about
| half the length of the spring is coiled similarly to drawing 4,
| with the upper half of the loose spring coiled less tightly and
| in the opposite direction.
|
| Because when our mainspring is exhausted, we want it to be
| bunched up along the outside of the barrel so we get the most out
| of it before it needs to be retensioned. And when it's fully
| retensioned we want to get maximum energy storage from the
| hardware so at that starting point we want the coils to be tighly
| wound, bunched up around the arbor.
|
| But not too tight.
|
| Or it could be _overwound_.
|
| As long as there is some space in between the coils, when
| recovering rotational energy you have access to what is stored
| along the entire length of the free portion of the coil. But once
| it's wound tightly enough for the coils to be in significant
| direct concentric contact, the free portion of the coil becomes
| so small it does not contain enough energy to drive the
| timekeeping mechanism.
|
| It could get so tight that it's not much of a spring any more.
| Closer to a solid cylinder with a slight tab hanging off.
|
| Which is more of a problem when both ends of the torsion spring
| are permanently attached to their substrates.
|
| Instead in these drawings, the color-coded _metal strip_ is used
| to provide a friction grip between the outer end of the coil and
| the barrel, strong enough grip to drive the timekeeping mechanism
| but designed to slip counterclockwise within the barrel if manual
| winding proceeeds more than necessary, slipping before the coil
| can get wound too tightly.
|
| Basically, overcharge protection for a non-electric hardware
| device.
