I too am on the search for blue hydra. I love that color. I think it was available when the Hermes website was available. I didn’t realize I would like this band so much. This is like my 2025 Kilim!!!! I am on the hunt for that blue hydra!!!I really like all the En Mer. My Ultra came with the orange and I got the Gris, which is now permanently on my Ultra. Have got my eye on the Bleu Hydra….though like you my wallet wants a bit of a rest and wants to be used for real life rather than playthings. Well that’s what the wife says lol.
