The tide showing subdial got as addition on the right the blue or green color segments for the use at the Regatta start. These are some of the most beautiful watches ever made.
The introduction starts in the early 1950s. Seafarer is the name for the Mareographe in the U.S., distributed from Abercrombie & Fitch.
The Mareographe and Seafarer started in the 1940s/50s Chronograph cases (reference 2443 / 2444), was built with Heuer Carrera cases (2447) and finally at the end of the 60´s in the Autavia compressor (2446c) case with snap caseback in very nice 2 executions.
Only these Autavia compressor case executions were also distributed as Orvis Solunagraph (Orvis as mail order company for fishing equipment, founded in Vermont, USA in 1856).
Inside the Mareographes and Seafarer works a Valjoux 71 in the early ones and later the modified Valjoux 72.

Whats on the dial?
To know when the tide is coming and going is an essential information at some seas like in the northsea and on the atlantic.
The Marograph/Seafarer got 5 using scenarios:
