Patek has reference 5711 in brown strap as you said. I think you should order a custom strap as well if you really want that combination. My suggestion for you is to take ref 5980. Since for my personal opinion, i think your choice don't really match with a leather strap. (It is only a matter of taste i guess)
Nice one sir! Personally i would prefer this vs 5711. But it is depend on your daily use. If you want a multipurpose sport watch, i think 5711 is better for that
This one could be a great addition in your collection as it is very different of your 5711 (shape, complication, style...)

Nevertheless, regarding an annual calendar complication, I prefer the Gondolo 5135 which offers a better readability to his owner IMHO. But the style is very different of course.
The bracelet is not my cup of tea and I find the month and day markers a bit too busy. I prefer the month and day in windows. It is still a very nice watch.
