I never saw a Jeager Lecoultre Polaris II Blue, nor a Lecoultre Polaris II grey or Red...
I wonderi f they exist...
I was thinking about the JLC Polaris 65 and 68, but wording apart, they are too close from their american sisters... Hence the omission.
And I only considered the Vintage, hence the magic number: 7.
Best, my friend.
