Indicator The Moon phase indicator of this watch indicates the current phase of the Moon as shown beow. It is based on the view of the eft side of the moon at meridian transit from the northern hemisphere of the Earth. If the appearance of the Moon phase indicator is reversed from the actua Moon as viewed from your ocation, you can indicator use the procedure under To reverse the dispayed Moon phase to change the indicator. (part you cannot see) Moon phase (part you can see) Indicator Moon Age Indicator Moon Age New Moon Moon phase (part you can see) First Quarter (Waxing) (part you cannot see) Fu Moon Last Quarter (Waning) Tida Movements Tides are the periodic rise and fa of the water of oceans, seas, bays, and other bodies of water caused mainy by the gravitationa interactions between the Earth, Moon and Sun. Tides rise and fa about every six hours. The Tide Graph of this watch indicates tida movement based on the Moon s transit over a meridian and the unitida interva. The Tide Graph cacuates and graphicay represents current tide conditions in your Home or a port city in the vicinity of the Home based on ongitudes, unar day ength, and unitida interva preset in watch memory, and on high tide times specified by you. Tide Graph The Tide Graph graphicay represents the current tide condition using one of three patterns that represent spring tide, intermediate tide, and neap tide, as shown beow. Tide Name Graph escription Spring Tide Intermediate Tide Large difference between high tide and ow tide. Occurs a few days before and after a New Moon and Fu Moon. Medium difference between high tide and ow tide. Neap Tide Sma difference between high tide and ow tide. Occurs a few days before and after the first quarter and ast quarter of a haf moon. The Tide Graph fashes as shown beow to indicate the tide range. High tide Low tide The segments on either end of the Tide Graph fash during high tide. Lunitida Interva Theoreticay, high tide is at the Moon s transit over the meridian and ow tide is about six hours ater. Actua high tide occurs somewhat ater, due to factors such as viscosity, friction, and underwater topography. Both the time differentia between the Moon s transit over the meridian unti high tide and the time differentia between the Moon s transit over the meridian unti ow tide are known as the unitida interva.
