Hey guys, would really like to hear your thoughts on this one. Came to me through the grandson of a portuguese Navy officer (Portuguese import mark visible) who basically wore it his whole life mostly on a ship. Never saw a yellowed dial like this one, and particularly because it aged differently on the tachy outer ring. I can get it fairly cheap at 2.5k euros, love the provenance and the dial originality, but have doubts on later easiness to sell it. Any thoughts? Thanks!!
