Apple watch band
Can I buy an apple watch series 4 with a gold finish but with a black sports band or do I need to get the available colors with the gold finish and get a separate band?
Apple Watch
Apple does not offer a band swap option or the option to mix and match bands and cases when buying Apple Watch, whether in store or online.
When initially buying Apple Watch Series 3, it is only available in certain preconfigured combinations of band and case. All models that are currently available to buy (in the US, for example) are detailed here:

Certain bands are available to buy as a separate accessory, as detailed here:
If an included band will be surplus to your requirements, then you may wish to consider selling it.
