Classic buckle leather band for Series 5 Watch?

[Mr. 123]

Hey, I have a Series 5 aluminium watch and am concise Ring getting a second hand classic apple leather strap for 50 bucks, as they’re not sold anymore but I have read that they aren’t completely compatible with the S4-6 watches. Is this true? And if so, what kind of damage would it do to the aluminium S5?

I used to have a third party leather loop and nylon sport loop for my S2 but I don’t have them anymore and want to get another band than the sports and that came with the watch when I bought it.

Thanks in advance!

they're all compatible,
The only thing that matters is if it's the larger or smaller size. (an old band for the larger case, will work with the new larger case)
38 and 40 work together
42 and 44 work together.
