I have several multiples. Two Parmigiani Fleurier Tonda 1950s, two Monta Nobles, five (I know, I know) Axios Ironclads, multiples of several Islander models (two of the new Bayport and two of the orginal SKX model), and multiple Casioaks. I have been considering adding a BB58 925 to my BB58 blue.
I find if I like a watch, I want it in several colorways. If not, it doesn't hang around for long.
