Apple watch ultra ocean band extension

Does anyone have the ocean band extension and can help measure the length of it? Need to wear it over a drysuit and not sure if the extension is long enough. My current dive computer strap measures at 2.5 inches for the shorter half and 9.5 inches for the longer half.
