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 two versions sold as Abercrombie & Fitch Seafarers. To see the Heuer Mareographe and the Orvis Solunagraph in this same 2446C case, click here.
