Love Bangle, for sure, especially if you already have some nice watches. The love bracelet is just such an iconic, classic piece. I think if you got the J12 watch, you'd still want the Love Bangle down the road. Also, the idea of your DH giving it to you is very romantic.
P.S. I def don't think it matters that your friend has the bangle already. There is no monopoly on owning classic pieces such as this one.
So true on both statements! Especially the 2nd one, I feel much better now! thanks!
