Getting an iPod nano 6th gen as a "smartwatch" worth it ?

So I've been wondering on getting a 6th gen iPod nano as a kind of "cheaper" Apple Watch, without the phone fonction because I don't actually care about it.

Now, I know it's not sold anymore officially, but that doesn't matter; is getting an iPod nano 6 (Don't care how many storage) worth it ?
I mainly am looking for a nice mp3 to wear or have easily with myself on the go, but I'm also very interested in the "Watch" capacity the nano has.
(I already have an iTouch 5, but acts more a very small tablet and home player, while this nano would be used on the go).

I know I could get a new iPod nano 7, but it doesn't have the watch capability (and videos aren't that important, just looking for a nice fancy mp3).

Else, if it's not a good idea to get a nano, what else can do these things without having to have a phone; a device that works on its own ?

Oh, and also, do you guys know any good nanowatch straps ? That'd be useful if I end up getting one someday !

Thanks in advance for your replies !
