Abercrombie & Fitch Seafarer -- Main Page
Introduced in the early 1950's, the Abercrombie & Fitch Seafarers included a unique indication that had not been included in chronographs produced by other manufacturer -- 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.
