S.H.
·There are very dedicated watch "hypers" out there who will do whatever they can to counter that trend, because they know they would lose their shirts if that happens. In some circles you are only a true enthusiast if you pay inflated grey prices, and you are a low level chump if you wait for a watch from the AD to get it at list. The level of insanity out there is massive, and those people will do anything to keep it going.
I actually think some of the pricing is pretty artificial anyway, with watches moving back and forth between dealers, with widely publicized increases each time before they actually sell them to collectors.
The recirculation between vendors is a well known trick among low grade antique dealers, I would not be surprised if it applies here too indeed.
I agree about the level of insanity, for me it is mind boggling. Like meme stocks, disconnected from value and return; pure greed running wild.
I personally apply a criterion to see if a watch is overvalued (to me) : what is the multiple between routine service cost and market value. A sub costing around 500 to service valued 10k? A multiple of 20 is a sign of trouble to me, there is some kind of disconnect.
