Spare replacement parts for keepers in your collection
Certain brands keep their parts for 20-30 years after a product is discontinued but it seems a trend for companies to limit availability of parts to only their own service centers and charging an arm and a leg for them. Others do not seem to have a proper inventory of parts for discontinued pieces.
Do you purchase/collect spare parts for keepers in your collection that you intend to hold for a long time? Say spare donor movement, bezel etc etc? or worry only when its time to service the watch?
