The flyback reset must be clean and instant; any hesitation on the lower pusher indicates service need for a movement that deserves factory-level care.
Known issues in the market
Flyback reset hesitation indicates service need; the CH 29-535 PS should be serviced only by Patek or a Patek-certified watchmaker.
