Which did concern the Explorer, not specifically the 6610 which came in '55 if I'm not wrong.
So, it is not curious or contradictory to see this common litterature, it is part of the Patrimlony of the crowded and the rose brands.
But it is interesting, as is your watch, by the way.
This is something I have in my mind, to say all.
Thanks for your very interesting input, Guillaume.
Best,
Nicolas.
