I've been looking for someone to service my Pierce Chronograph (Cal.139) for a while now.


Everyone I've approached have said they can't get parts. Specifically the "plastic parts".


Does anyone know what these parts are?

What are the specifications of these "plastic parts"?


Has anyone tried to replicate these with a 3D Printer?


I'm wondering if I try to print the parts myself whether I'd have more luck finding a watchmaker to service it?


Appreciate any input or advice.


Thanks
