should you sell your entire watch collection for a watch that steals your heart (probably soul)?
Considering the fact that:
1) you have a good amount of watch collection that can fund 60-70% of your new grail watch;
2) Age (early-mid 30s)
3) Considering that your buying behavior (heavily consideration on resell value or value retention )
4) you good sir are aware of other options such as (PP, AP, VC etc etc)
before you make decision on purchasing, please consider the following too:
A) do you foresee yourself selling this RM in a decade time or anytime down the road?
B)what is the value retention for RM if you are selling it (check secondary market price)
C) if you buy a time piece, (aside from value holding or inflation hedging) what elements do you consider in a watch brand?
History (brand)>craftsmanship>aesthetic>Price Tag>rarity? (order of these elements is highly subjective)
In my honest opinion, if you dont plan to sell the RM in any future time frame, then please go for it.
(Maybe only for me) Liquidating your entire collection for a single watch that trapped your heart and soul, this isnt something that happens all the time (given the knowledge and exposure you had on watches). My guess is that given that you have reasonable knowledge and info on luxury watches, all the hot models from the top notch brand should be made known to you. If those hot models of other brand doesnt catch your eye or doesnt give you the idea of liquidating your whole collection, this means something (they dont worthy such 'leap of faith' / 'all in' emotions).
Also, part of being a watch collector, not only I find joy in owning some hot/discontinue models, the hassle and waiting/hunting is also part of the enjoyable experience of being a watch collector.
Maybe you can get the RM first, then start filling up your collection again in future times.
hope it helps. (congraz in advance for your new watch!)
