I am a huge fan of Longines, given even my username here a Longines portmanteaux.
My opinion is that Longines have that roots of heritage, that is unique.
Nowadays the house made affordable watches for a lot of people, but it have a charism that appeal to me.
Nicolas, enjoy your great Longines, and do not sell your Longines. I do not use the word it, because something great is not an it.
