By the way, few owners of 40,000 dollar watches, other than gangsters for whom every day they put on their watch can be their last with an arm to wear it on and eyes to see the dial, wear them every day to show them off.
Some collect watches, and only take that watch out for a very special occasion. Some of those watches appreciate in value years down the road, so they make a nice yerusha and yes, even can be sold or donated for resale for tzedoko or borrowed against to support a learning child. (I don’t think they’re worth it as a plain investment unless someone truly enjoys having such a watch.)
