A piece of history.
The story of this watch is not entirely unknown, it has sailed overworld seas. And hade some great adventures with his owner(s).
If you take a closer look you can see it is a typical 40s chronograph. The shape of the crown and pushers, but especially the dial. All the lines to calculate which way to go for how long. Almost looking like a historical map.
So are you the one who continues the story of this watch? A historical watch with all the old elements.
