New Apple Watch bands

Hi

I'm afraid that no-one here can tell you anything about Apple's unannounced product plans (this is a user-based community).

Watch case and band combinations that are available together as an initial purchase are not necessarily complimented by separately available bands (ie when purchased as separate accessories).

The same principle applies to buckle colours for Apple Watch Woven Nylon Bands.

If you would like to suggest that Apple considers adding additional Sport Bands with differently coloured pins, you can do so here:

Which band are you referring to? I'm guessing you meant the Sport band, in which case they already have them. For example:

Note that if you buy the band separately, the pin is only available in silver. You can only get one matching the color of the watch if you buy the watch itself with that band.
