From sailing to sandcastles, we all need to know what the tide is doing. Synchronised to the lunar cycle, the tide clock provides an innovative & convenient guide to tides. Simply set the 'tide' 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 & 25 minutes around the coffee cup fascia, giving you the state of the tide at a glance.
