In other words, if you feel like congratulating yourself on your minimalism, you can pretty much justify anything as minimalist.

Personally I'd say that the minimalist wristwatch option is none at all. I don't think I'd be happier with no wristwatches, though. While my wristwatches bring me only a minimal amount of pleasure, congratulating myself on my lack of wristwatches wouldn't bring me much pleasure either.

I prefer "vaguely appropriate scale"-ism to minimalism. No wristwatches is too few, ten is too many. Pick something in between and stop fretting.

Very good point. Sometimes minimalism is a lot more expensive.
