A great collection of Navi's Fred. It won't surprise you to know my favourite is the 1955 all black dial.
Yours is in gorgeous condition. What a stunner! I always think these early Navi's don't get the sort of love they deserve, compare them to say the obsession people show over Speedmaster details - not to mention Submariner variations. Also in 1954 this watch must have felt HUGE! Breitling pioneered the big watch.
Just to add some more stuff to your great thread here are a few early Navi's in the wild.
The king of cool. Miles Davis,
The King of XXXX. Serge Gainsbourg.
Scott Carpenter - okay it's a Cosmonaut, but it was called a Navi first!
My 1960's all black.
