The aluminum is softer than the SS model you are used to. As such, it is more likely to suffer a ding, chip, or dent if hit hard against an opposing surface.I’ve always had stainless steel AW since day one. I’ve upgraded to every new iteration and held on to my series 4. but decided it was time to upgrade to series 7. But this time I went with the midnight aluminum. I’m not concerned with aesthetics, but I am concerned with durability. I’m not too rough with it but it does get banged around occasionally at work and I am very OCD with even minor dents or scratches. I can polish my SS whenever I see some light scratches and it comes up brand new. Will the aluminum take a noticeably easier beating if it gets lightly bumped and banged?
This year will be the first for me with aluminum since I had account credit to cover getting a new watch. I usually go SS. SS is very nice but, the extra cost adds up especially if one upgrades every year. I got AC+ with the watch since it is much more likely to suffer damage than my phone. If something does happen, hopefully, I can use AC+.
