Why is it that all Watch bands only go up to like 220mm, yes there's the Ocean extension and the ONE XL Midnight Band but that's it. I would think they would provide a larger band version with the Ultras but it doesn't seem like it. I know it is a newer device but maybe with the Apple Watch Ultra 3 they could introduce a larger band size. Or if the rumor mill is correct that there's gonna be an Apple Watch with an even larger display they could introduce another XL band alongside that. I personally just have big wrists and want to comfortably wear my watch but use proper Apple parts with my devices.
