Peek-A-Boo I think if you just want a band with clock function and some notification function, I think you can do with any fitness band or Galaxy Fit e or Galaxy Fit.
If you want more feature and money isn't a problem, Watch Active / 2 or Gear Sport or even their Gear S series won't go wrong.
Personally, I don't see any specific watches designed to be paired to only specific phones, yet. What looks good when you wears it is what I presume as the best, suitable for you,...regardless of what type of phone you used. 👌
