Hi there, I did have a search through but wanted to ask a question

(As of 2023) I would like to get an apple watch however solely for the single purpose of Camera Control. (Native Camera app and possibly GoPro) what option is best?

I dont fully understand the series’ and SE and looking to just get something pre-owned/cheaper off ebay. The only thing I care about is that the mirroring is flawless/instantaneous so I imagine maybe older watches are a bit slow but that could just be guessing.

Thanks!
