Thank you for posting this amazing picture Jeff, it is a lot of emotion for a Seafarer/Mareographe enthusiast,
I'm definitely one of them.
Well, I'd be tempted to say I love them all and it's true but to be fair and play the game my AbFav remains the 2447 case execution (I still take a deep breath each time I put it on my wrist, this watch is still so emotional to me)
and, if I'd have to make a second choice, I'd say the one pictured on the center, very very nice !!!!!
But they're all absolute beauties and deeply interesting as toolwatches, one of Heuer best effort to me.
It is a shame to me the Heuer productions related to the sea (Seafarer/Mareo, Skippers, Divers) do not have the recognition they deserve,
but it is a luck for the enthusiasts collectors, niche collections are so rewarding !
