Abstract
A watch or other instrument for graphically displaying tide and time conditions and for determining tide conditions for a date and time in the future. Conventional watch functions (21) are combined with computing circuitry (FIG. 2) to continuously update and show tide conditions by means of tide height bar (29), and tide direction indicators (22, 22). Future tides are indicated on the same display when the Future Tide mode (33B) is selected thru buttons (5, 6, 7) and the selected date and time is entered.
