Unless you have a specific need for stainless steel Apple watches (e.g. sapphire glass, better aesthetic), I would recommend to get the latest generation of tech products that you are willing to pay.

Paying for better material on a regular watch makes sense to me as I’ll keep my watches for a very long time, may even pass to the next generation(s). However, I’m fully aware I’m going to upgrade my Apple Watches (or tech products in general) every few years, I just don’t find the added cost to be justified.

What are you doing with it?

SS looks a ton better imo, especially for fancy occasions. That being said I have an S7 Midnight Aluminum. I Longboard, Snowboard and such and have Applecare plus in case I break it. I don’t mind scratches either as I think it adds character. I got mine at Launch day from an S2 and it’s still going strong with no issues.

I would get the Apple Watch Series 9 Aluminum
