that if you can service one grande sonnerie you can service another.
The problem is certainly how many people have the training to service such a complication at all.
I remember the people in the sonnerie shop at Daniel Roth telling me
that they each produced about two watches a year and serviced two
watches a year. They were 3 or 4 watchmakers. That's not an
awful lot of sevices each year.
I would not want to give my hard earned repeater to any old
watchmaker. They would certainly enjoy the possibility to play
with such a piece, but without the necessary training I would have my
serious doubts to getting it back running better than before the
service.
