Let me examine your concerns one by one.
(-) It's not a perpetual or even a annual calendar so the complication is not that exciting or ground breaking.
As amanico pointed out, the perpetual is available just in different case sizes. The Master Ultra Thin Perpetual is slimmer (http://www.jaeger-lecoultre.com/US/en/watches/master-ultra-thin-perpetual/1302520#/t1) and the Master Eight Days Perpetual (http://www.jaeger-lecoultre.com/US/en/watches/master-eight-days-perpetual-40/1612420#/t1) is very slightly larger.
(-) The movement in the display back is not that well decorate and looks boring
The MUT Perpetual isn't any different in that regard. The Master Eight Days Perpetual, however, has a more interesting hand-winding, 8-days movement ... if you like the dial first, that is.

(-) JLC generally poor resale value, a concern if I need to sell the watch in future
Okay. That seems like a universal truth across the board for this brand.
(-) A bit of a duplicate with my Patek 5205
Uhhh.... I'm not entirely family with Patek numbers but I think the Master Calendar looks more like 5936 than 5205? I'm looking mainly at the dial of course.
I personally like the Master Ultra Thin Moon suggested by JML. Its eggshell dial is very desirable as Spellbound noted. But wrist presence may be more subdued than your original choice. The Eight Days I bring up may have the movement that pleases you more but then its dial is quite busy.
Dilemma, dilemma, so good luck.

I need to know more about your tastes. According to your picture, you are after a classy, elegant timepiece. Of course, this Master Calendar is a nice option. Is it necessary to get it in rose gold? Isn't the SS version " enough "? The Master Calendar is ...

Hi As has already been suggested do you need the rose gold version - steel Jager leCoultre's still look fab, then if there's too much replication with other watches there's the Master Ultra thin Moon. Which is really elegant and different to annual calend...
I second that

I think the MUT Moon in pink gold with the beige sunray-brushed dial which someone described as "eggshell" is a gorgeous warm watch, elegant and simple. But if you insist on the Master Calendar, I would opt for a vintage triple calendar as I feel the new ...
Thanks All

Hello benlee338! I'm biased on this watch. My first JLC was a Master Moon in stainless steel with a black dial. To me it was functional, had a cool clear case back, and reliable. Have you considered this one: -MW ...

It was a gift from my father for a significant birthday (coming up next week). I ultimately chose it because of the complications, classic styling and pedigree of the brand (I also own a vintage steel JLC triple date from the late '40s), and in rose gold ...
