bro, you said you prefer any shape Except Circle
which mean rectangular, triangle, square or whatever not circle (round)
and you started to worry on resell value
as far as i know not much resell value for rectangular, triangle , square shape watches if you can find any
the only one which is good looking and hold value is the JLC Reverso series
but that one more your expected budget of below 5k
Tag Monaco series also nice but still above your budget, unless you are willing to pay more
Cartier Tank also nice
