Apple has accidentally released images of a Space Gray Milanese Loop for the Apple Watch. This image was found on Apple’s Czech Republic store website. It has since been removed, but it’s a good sign that we may see a new color band color.
Right now they only sell this band in silver. There are third-party models in Space Gray, but not from Apple. The current Milanese Loop is available for both the 38mm and 42mm watches. It costs $149 and works on all Apple Watch models.
