This Mareographe from the 1970s was produced for the French speaking market. Its name comes from the conjunction of Marée which means tide in French and Graph which means writing in Greek so literally, this watch presents itself as the tool watch to time the tides.
The present watch also distinguishes itself by the signature found on the dial. When most of the Seafarer or Solunograph models were retailed by Abercrombie & Fitch or Orvis, a very small portion of the production was kept by Heuer and sold under its own name. So rare were the latter that less than 15 other examples have surfaced until now.
Presented today in very attractive overall condition, we cannot fail to notice the superb metallic graphite grey dial perfectly preserved thanks to the compressor case that offered 100 meter waterproofness.
