Tide Clock - with hours diplayed until high and low water. Synchronised to the moon's daily cycle, the tide clock gives you an innovative and convenient guide to tides. Simply set the hand to the full tide position at exactly high tide for your chosen location, then throw away your tide table! The quartz driven hand will rotate every 12 hours and 25 minutes around the solid stainless steel fascia, giving you the state of the tide at a glance. This design also provides an indication of how many hours remain until high or low water. Brushed solid stainless steel finish and 195mm in diameter. Wall mounted.
