the luminous compound is beyond repair, and will fall into the movement if not replaced
the dial with the old compound removed
proposed colour for luminous compound
new compound on dial
low amplitude - the hairspring is slightly deformed, and touches the spokes of the balance
the hairspring is deformed a bit - looks like a dish rather than a flat spiral
the hairspring is deformed upwards
to re-shape the hairspring, I bend the overcoil outwards
now I can pull the hairspring downwards to make it flat again
now I can bend the overcoil back, and the hairspring is back to where it should be
now I've got a decent amplitude, and a hairspring that doesn't touch the balance spokes any more
