I’ve always preferred the look of the oyster and its great on my sub.
However, I like the jubilee on the gmt, and adding a gmt alongside the sub, for me, the jubilee adds a worthwhile differential, along with the more colourful bezel and gmt complication.
I have liked the blnr as a watch, but I’ve always thought it looks too much like my sub to warrant owning one as well as the sub.
I am however patiently on the waiting list for a Pepsi gmt!
So for me, if only one Rolex, oyster, but jubilee adds a nice bit of variety as an addition.
