Tide Clock - contemporary, minimal design. 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. Brushed solid stainless steel finish. 195mm in diameter. Wall mounted.
