Using miles for watches?

Seems like a terrible use of miles and likely not the best value, but I suppose if someone was sitting on a pile of miles that they knew they weren't going to actually use for travel...

Those are links for United Mileage Plus shopping; I'm assuming the other major airlines have similar offerings since many of them use the same platform / vendor for their loyalty rewards programs (which on a tangent was in the news last week because of some security vulnerabilities found, reported, and fixed).

It's similar to the age-old Q about redeeming points for domestic short-haul flights in Econ vs FC tickets to another continent. At the end of the day, if it's something you want and it makes you happy, go for it.
