Everything you need to know about lunar time.

The moon orbits the earth every 24 hours and 50 minutes (the "Lunar Day"). Because the moon is the primary force moving the tides, our quartz movements are tuned to this exact cycle.

2. Set the clock to the 'High Tide' position at exactly that time.
3. For maximum precision, do this on the day of a Full Moon or New Moon.
