There were six versions of the Mareographe that used the Reference 2446C (compressor) case from the Heuer Autavia -- the Heuer Mareographe, the Abercrombie & Fitch Seafarer, and the Orvis Solunagraph models, with each of these produced in an early execution and a later execution.
On this page we show the Heuer Mareographe and the Orvis Solunagraph. To see the Abercrombie & Fitch Seafarer in the 2446C case, click here.
