This is a purely theoretical question I thought I would pose to the rest of you vintage watch collectors out there. I've seen others here talk about their collections with phrases such as "this is part of the unworn section of my collection" and I got to wondering how it would be best for a collector with a finite amount of money to store their peices.
Obviously, all the peices in the "to be worn" section need to be serviced. There may also be a section of peices that you never plan on wearing, which you can let sit there (so long as they aren't full of corrosive agents or natural oils that might break down into corrosives or thicken up until the mechanism is seized) without servicing, assuming the peice is in decent-looking condition. If, however, you buy a watch that you would like to preserve, but you don't plan on wearing it in the next five years, would it make sense to have your watchmaker do a service in the normal fashion, but without oiling it?
You certainly wouldn't want to accidentally pick up one of the watches that you didn't have oiled and thoughtlessly wind it to see it work if it was bone dry, and the automatic movements cab easily be wound at least partially by accident, but if you were just going to have then in a display cabinet would it hurt them to be sans lubrication? The idea that is trying to be resolved in my head is that maybe you would pay for a cleaning, and sure, it would cost the same as if you had oiled it, but if you could put off oiling it then you wouldn't have to pay your watchmaker for the full service if four years down the road you decide to have him oil it so you can move it into your "wearable" section of the collection.
I'm no watchmaker, so I don't know the full extent of what sort of disassembly is required for an oiling, but my guess is that you don't have to disassemble the watch as far as would be required to do a full cleaning. If this is the case, then it would make sense to do a full cleaning, then postpone oiling the watch until you decided to wear or sell it. If, however, it would take roughly the same amount of work to oil a clean movement as it would to clean and oil it, then the thought can be put out of my head.
