Useful tips :
We recommend you to set the clock at the high tide and preferably on the day of a strong tidal coefficient. For a more accurate setting, pick a full moon date. Note that the tide times vary by location. Not suitable for navigation.
1/ Check information about the local tides coefficients & schedules on a local tide table, or check the following website http://maree.info/
2/ Pick a day of strong tidal coefficient (from 85).
3/ Set the single hour hand using the wheel at the back of the movement to indicate high tide on the dial, insert then an alkaline AA battery
