Anyhow, there are certainly a few different prudent ways to balance out some kind of spending of BTC in this price area.... Of course, some of the devil can be in the details, too, such as how much of your stash are you spending, and where are you at in the process of accumulation, maintenance or liquidation... and of course, there are some other considerations that might factor into the matter too.
It's always tough to sell bitcoins for frippery, but at the same time I don't want to die suddenly with a huge stash. So a nice thing every once in awhile can be fun even if you realize the nice phone you bought a few years ago is not worth $6,000 today :-)
By the way, you are mentioning that you really want a watch, and watches can have some utility, status and cosmetic value. A few years ago, I had thought that I had graduated away from wearing watches, but in recent times, I had also returned to wearing a watch, so sometimes we don't really realize some changes that might just come upon us, perhaps watches are coming back into fashion a bit in recent times, too?
They can be things of beauty. They can also be exceptionally flashy monstrosities which I guess is beautiful to some people. For myself they have both utility and beauty purposes and remind me that I always have a backup skill (watch repair) that I can fall back on if I get sick and tired of my current profession.
Part of the reason I prefer to wear a 12s or a 16s pocket watch instead of an 18s, too flashy.
