Indeed they look great with the colors you mentioned, I'm going to wear them on the weekend 👍.
Yes, I had about 4 modern buckles, I gave that watch to my sister with bands and everything. At first, I was in denial that the big watch didn't fit me, but I got rid of that idea and haven't gone back, I tried but I never liked the smaller watch.
In fact, the same thing happened to me with the Ultra, I usually change watches on launch day along with my iPhone and this time I couldn't decide on the Ultra. It took me several visits to the Apple Store to finally buy it, like at the end of November, and I don't know why I limit myself at first if I know what I want and as I told you the Ultra has been my favorite Apple product ever since.
