Orvis Solunagraph -- Main Page
Heuer Introduced its line of "tide indication" chronographs in the early 1950's, with these chronographs being marketed by Heuer under the "Mareographe" name and by Abercrombie & Fitch under the "Seafarer" name. These chronographs included a unique indication that had not been included in chronographs produced by other manufacturers -- a tide indication. The dial on the left, at 9:00 (nine o'clock), shows when high and low tides will occur. Specifically, the cross in the center of this dial indicates the times for high and low tides, with the disc turning to match the moon's orbit. Accordingly, the points of the cross are not 12 hours apart, but are actually 12 hours and 25 minutes apart, to correspond to the cycle between high and low tides. The pusher on the left is used to set the disc for the correct high tide / low tide times in a particular location, and the disc then rotates to remain accurate.
Most of these tide indication chronographs produced by Heuer were sold under the Abercrombie & Fitch Seafarer name; however, Heuer also sold these watches under the Heuer Mareographe name. Around 1970, Heuer began producing Solunagraph chronographs for Orvis, a retailer of fishing equipment.
