IMHO probably the best wristwatch UN ever made! A founding watch for UN, even more, again IMHO, than La Trilogie du Temps.
Well, add to this a UN wristwatch with Peseux 260 [yes, they exist as a wristwatch ], a ship chronometer, a nice chronometer rattrapante pocket watch, an observatory pocket watch
and you have the perfect UN collection...
Best,
