How long does it usually take for 3rd party accessories to be available? I'm looking for some bands not offered by Apple and a robust protector when doing exercise.

Old bands should be fine with newer models of Apple Watches.

Size-wise yes, but I doubt I'll find connectors with the same color as the series 7 watches have.
