First of all, welcome!
It’s a bit hard to advise you since which watch you prefer is really a matter of personal taste. Here are a few things to consider though:
- If you are someone who will be bothered by a mismatch between your watch and the lugs on the band (i.e. black watch with silver band lugs), be aware that Hermes only makes a handful of bands with black hardware (and those bands are all black except for one of the new Jumping single tour bands).
- The silver will give you many more options when it comes to bands since all the brown and colored leather bands come with silver lugs. With a 40mm model, you could also pair Apple’s Modern Buckle bands for additional leather options (most of these have silver hardware too). Lastly, the vast majority of Apple’s sport bands have a silver pin.
- The silver will look more like a traditional watch. However, it will also pick up micro-scratches over time (these can be polished out).
- The black has a bit of an infinity look to it. You can’t really tell where the screen ends and the case begins. The DLC black coating also makes it extremely resistant to scratches.
- The silver comes with an orange sport band. The black comes with a black sport band and also has an extra Noir watch face option.
So, it really comes down to what you want. If you would rather have a bit more of a traditional watch look or want to be able to pair lots of different leather bands, get the silver. If you want the watch to look as if it were a singular piece of glass or you are only planning to pair a single black leather strap, get the space black. Both are great!
