JLC blue is amongst the best!
And I love these characteristic hour markers when they use them.
The markers reflect sunlight as if they were diamonds...
My other two favourite blue dials are the ones on the FPJ Chronomètre Bleu and the Vacheron Constantin Overseas.
Magnifique!
Beautiful watch on a very cool strap : can you tell us more about the strap? Its a blue that definitely calls for an ocean view!
