116520 vs 116500

[heath.1967]

Hello guys i have question,im between 116520 black dial and 116500 i was offered both in very mint condition and both come in fullset,i have question do you guys think that the extra $8,000 for the 116500 is worth it ? because i see that the major Difference is only on the bezel and slightly updated movement,and also which one is more blingy and would retain the value better?
in my humble opinion for the 'investment' value the 116520
and for the proportion of the watch i think 116500 is a better watch
thank you so much guys
