These are a few examples and probably exaggerated ones at that. Of all the different watch models produced each year 99.9% of them sell below MSRP the moment they leave the store and frequently even before they leave the store.
At the end of the day, the MSRP is a guess of the right price given the manufacturers intended supply combined with how they want to position their product from a marketing point of view. Periods of time in any product where the demand outstrips supply either by chance or on purpose are not exclusive to watches and in occur in luxury goods of many types. However, where they occur, they are typically the vast minority of products on offer. For example limited edition Ferrari models that sell well in excess of MSRP against a backdrop of other models that sell way below MSRP in the secondary market (for example compare F12 or La Ferrari vs the GT4 Lusso).
