Having ALU for the Series 1, 2, and 3 I was totally happy as I didn’t see any noticeable dings to the body or scratches to the face; and I’m a total clutz when it comes to banging my watches into door jambs and the like. Then, it finally happened, nailed my S3 against a door jamb and did a number to the screen. Like others said, once you see it, you can’t unsee it. So, I grabbed a S3 SBSS and have worn that for a few years without any dings on the case or the screen, and I continue to be a clutz, so it’s stood up to my abuse.
I skipped the S4, but just recently picked up an S5. I bough a Space Gray ALU first, to see if the S5 was enough of an upgrade for me. It was, so I sourced an SBSS and took the Space Gray back. I’m happy.
Except, when purchasing the SS, I took a look at Apple’s buy-back for the S3 SBSS - $70. Yeah, no thanks Apple. A $750 initial investment returning less than 10%? Sucks, but that’s how it goes, I suppose.
Anyway - if you are rough on your watches and/or can’t stand seeing scratches, the stainless steel, especially the SB version, would probably be your best bet if you can swing the price.
