fibre on the ratchet wheel
huge beat error
dirt in the pinion
this mainspring wasn't changed recently
the movement hasn't been cleaned at all
dirt everywhere

beat error 0.2ms - sorry for the blurry photo...
the luminous compound of the hands is flaking off, and dust will get into the movement if we don't replace it
new luminous compound in an aged tone applied
new crown and winding stem
