路I was very lucky with this one Mr Man. One pusher was sticking as the gasket had 'emulsified' apparently. So a new pusher gasket, new small chrono hand, new plexi crystal, a darn good clean and a service of the lovely cal.11 ticking inside. Job done.....(as I say, very lucky!)
For example, do the work yourself or a specialist watch repairer, collect the parts yourself, genuine or generic crystal, etc....
