Sorry to hear.
While, superficially, it seems like it could well be just the glass … the fact that you yourself aren’t sure strongly suggests to me that you have zero experience in repairing modern electronics.
I mention that because a smartwatch is one of the most challenging examples of modern electronics to repair. It’s small, its innards are delicate, and it’s more important that its environmental sealing be intact than for most other devices.
Which is all to suggest that you probably don’t want to attempt this repair yourself unless you’ve already resigned yourself to the watch being irreparable, and any money you spend to try to fix it by yourself is for entertainment purposes only.
If you have some attraction to this particular watch, I’d suggest taking it to a shop that has the apple authorized service provider badge. I’m pretty sure Apple themselves won’t repair the watch — and certainly not for any sort of a reasonable fee. But a certified third-party shop would probably do a good job.
If money is especially tight, take it to a shopping mall mobile device repair shop. They’ll be your least-worst balance between low cost and just throwing your money away.
And if none of that applies, just get a new watch. A brand-new SE costs $250 (base model) and has at least as much functionality as your Series 4. You could buy a used watch for less, of course — with a decent-condition used model costing not that much more than you’d pay a good shop to repair your broken one.
I know there are all sorts of reasons one might think it nuts to throw it away (preferably by returning it to Apple for them to recycle) rather than repair it — treating something superficially durable as disposable, the environmental impact, the cost, and so on. I’m right there with you. But that world hasn’t existed for at least half a century, realistically, and this is the world we live in today. Even if you want to change the world, repairing it yourself is likely not the most effective use of your own resources to do so.
Cheers,
