Apple Watch Sport collection vs Apple Watch Sport, Milanese Loop vs Leather loop. There are lots and lots of choices when it comes to configuring an Apple Watch. There are even two sizes to choose from—38mm and 42mm.
Choice is good, and there's certainly a lot of decisions to make when it comes to Apple Watch configuration. But when it comes to size, I would recommend the 42mm. Unless you have really small fingers, and a really small wrist, I think that you should at least try on the 42mm version to test it out.
Why am I so high on the 42mm Apple Watch? It's because I've tried them both. At first I didn't think that the difference would be that big of a deal, but after going hands on with both, I'm leaning more heavily towards recommending the larger version
