so this is a at a six four nine seven
movement it's a basic manual line
caliber with hour and minutes mounted in
the center and sub seconds mounted than
nine o'clock side see simple movement
good easy demonstration one so the parts
that we have here this is the setting
mechanism the set lever jumper and
bridge here is what differentiates
between the setting and winding position
so you can set the time push it in to
wind and then in the center here we have
the cannon pinion this is the clutch on
this movement that differentiates
between when you set the watch it slips
so the wheel is able to turn without
turning the rest of the gear train with
and then when it's normally running it
turns freely and has the minute wheel
mounted on it disassemblies
the canon pinyin is pushing down nice
and tight and use this tool to grip it
and pull it off you'll see the bridge
sided movement so that was the dial side
that's the fate of this site that
actually has the dial on top of it is
the bridge side or the back of the
movement where basically all the actual
mechanisms are that run the watch it's
the only really a dynamically moving
part of this watch too so it's pretty
eye-catching
and we have the escapement underneath
that this is a Swiss lever escapement
it's the most common escapement it's
pretty much the industry standard these
days this is what actually distributes
energy from the barrel the power
mechanism on this watch to the balance
before taking that out we need to let
the power down this Met has a power on
it right now okay so I'm gonna let the
power down
get a shot of that that's the palate
fork this is the half of this game and
the other half is the escape wheel which
I'll pull out in a second so now I've
got the gear train which is this is the
system that carries energy from the
barrel to the escapement it's a very
simple four wheel gear train
so you can see their rubies and bearing
surfaces there here's the gear train in
the escape wheel which is the other half
of the escapement this is a wheel with
asymmetrical teeth you have the fourth
bill this is got a long pivot that goes
through the dial side and this is the
the wheel that has the second hand
mounted on it and this watch and then
the center wheel is Mariam it's mounted
under the barrel bridge I'll get their
necks so I take out the screw for the
ratchet wheel and then also the crown
wheel here this wheel actually has a
reverse threaded screw so a left-handed
screw so it rotates left-handed because
if it were the other direction when you
whine the watch it would actually have a
tendency to want to unscrew the screw
and if a screw comes out while the watch
is operating it's basically gonna stop
functioning gonna cause some serious
damage having parts floating around in
there and basically from a customer
standpoint if the screw comes out of
your watch it's gonna stop and you're
gonna bring it back and you're gonna be
very upset
okay so here's our center wheel now able
to come out and then the barrel this is
the wheel that houses the mainspring so
this is the power source on the one you
can open it up and see the minutes for
you
so there's the spring coil in with an
arbor in the center basically this Arbor
has a hook on it so as you wind the
watch it hooks the end of this spring
and coils it up and stores the energy so
this is the unwound state with the
spring on the outside what it's well in
the spring we'll all be occupying the
inner space of the barrel feed this
mainspring out slowly
and that's a six point seven very very
simple mechanism keeps great time you do
all your adjustments like if this is a
watch we're actually servicing anything
that needed repairing it would be done
during disassembly and then the watch
would go into the cleaner everything
would get cleaned and then reassembled
and oiled when it comes out
