Why don't smart watches use USB-C to recharge?

As I understand it you can do USB-C at a basic 5V level with 2 resistors, and for a watch that would be plenty of power.
yeah but that wouldnt be USB C because usb C is a standard that requires a ton of different things like double way data and power rails and handle 60watts etc. If you just need 5v then you can do it in a much smaller way via another connector or even wirelessly.
I'm gonna assume you know more about this and I do because i cant even light up an LED in a circuit.

It does not work with either my Fenix 6 Pro Solar (specifically that one, other Fenix 6 variants are listed as working) nor the Forerunner 230 that somebody just gave me. Both of which are a drag, and I can't be arsed with learning how to add my own support right now at this minute.
Honestly, I've just been using my Fenix unconnected and it's really surprising all it can still do. The only function I don't have that I cared about was receiving notifications. The sensors and topo map and all still work fine and you can even still track rides and hikes, but you have to offload thr GPX tracks via USB and figure out what to so with them yourself.
It's almost like the dumbass limitations of the app are all just artificial, to the surprise of absolutely no one.
Yeah it's a shame the path Garmin is going

USB C is only the plug… USB 3.2 is the specification
USB power delivery is part of the specification that you can support without support for the other parts and is incredibly simple to implement by itself

USB C does not require all applications use all aspects available in the current spec (USB 3), that’s just silly. Take the latest iPhone for example (not the pro series,) they are all essentially running USB 2 through a USB C cable. And that’s perfectly fine.
The real problem is when a company uses USB C but follows none of the wiring or standards requirements for any standard. Such as running power over data pins making the charger some proprietary Frankenstein of bullshit.

You don't need to follow the entire spec for a usb c. Usb c has a display port mode, but most laptops that have this won't have it on every port. Most usb c cables also don't support display port mode, which is annoying because they usually won't say if it supports it.
Usb c extension cords are not allowed and yet they exist

A standardized magnetic pogo pin connector
That's something I hadn't considered before. What a neat idea.

The charging base is just breaking out the 5V of the USB to the pogo pins!

This sounds like an authoritative post. Thread over.
Unfortunately it's a bit of a misinterpretation. Yes the overall USB C spec is complicated, and cables can support different things without being labelled clearly, but you can use it just to deliver power much more simply.

Some watches already have USB - C. but I find it interesting to see if you are correct or not.
I would see standardizing wireless charging as a decent alternative...if it didnt take up even more space.
Some do, but the limitations of usb C (or any physical plug) are present and while it sounds nice in principle to have all the devices use the same cord it’s in general not worth the sacrifices that others have mentioned like it taking up extra room and the increased likelihood of water/sweat/particulate ingress

The good Garmins last 2 and half months no charge. An hour in the sun adds a week. Ink display and solar glass. It's awesome. In the smart watch health space garmin is second to none. Especially so for battery.
As a current Garmin user I really like a lot of the features of the Garmin but the app for smart watch health tracking is atrocious and some of the values you get are clearly wrong like it recording my resting heart rate at 15 bps lower than it actually is.
The battery life is still insane which makes things like sleep tracking really nice
