I don't know nuthin' about Garmin watches, but a quick check around the internet tells me that there must be a couple of different watch screens out there.
To start with, the first video I came up with shows a watch being opened, and it has the same kind of screen as the replacement you bought; take a look about 1:38 into it.

Looking into replacement parts, I see both kinds being sold. Here's one on Amazon that looks just like the one you have.

I'm not sure how you were supposed to know the difference between the two before you opened the watch, but now that you have, you can visually check that the replacement part matches your original.

I'd say it seems pretty obvious at this point that you're going to need to return the display you bought and get a different one.
