Hi Martin, the weight is a weak part of the caliber 11-12. Gets loose very often!!the weight is pressed on a exel, when its loose
it touches and scraches the uper Chrono-module. the winding mechanisem is not working perfect anymore and the watch has no power reserve! Not good at all.
I offer NEW old stock Weight as complt.Heuer- part ref.no.1143/1 or only a exel for repairs. Please feel free to email me when you need help.
greetings Jasper from Germany

: Hello all,

: I turned my perfect running Autavia Automatic
: Cal 12 today in an unusual and fast way
: upside downside (don't ask me why) and there
: was a kind of click I never noticed before.I
: assume that this clicking sound comes from
: the oscillating weight. So this is my
: question: Is this the usual tolerance of the
: oscillating weight on its arbor? Or is
: anything broken? As I mentioned above: The
: watch is working without any problems,
: including the automatic winding device.
: Someone told me some times ago, that the
: arbor of of the oscillating weight is a weak
: spot of this movement. Thanks , Martin
