New member here. Love the forum.
Some of you watch collectors mention keeping wathes in the vault, meaning that they are not worn but are collection pieces. Isn’t it true though that if a watch is not run that the oil inside will dry or coagulate and the gears will stick and then it will need servicing?
If watch is never worn or wound, kept in the original box in mint contition with the tags still on it, won’t it still need servicing after five to seven years anyway?
