the amplitude reading isn't correct - the balance barely swings
lots of dirt everywhere
as I thought, the oscillating weight spring is broken
a lot of dirt in the gear train
a lot of dirt on the centre wheel, too
all the parts cleaned up very nicely
balance jewels in place
the new banking stop spring is in place
the pre-tensioned mainspring in the barrel
the movement is back together
the watch looks a lot nicer with the low dome crystal
