All Driftwood Designs clocks are designed by Lizzie Spikes in Aberystwyth and made in the UK.
The tide clocks are 250mm diameter and of MDF construction with a printed vinyl face.
Setting the tide clock – establish your local high tide time by checking a tide table. At exactly high tide set the clock in its high tide position (hand pointing straight up). For best accuracy across a calendar month, set or re-set the tide clock on the day of a full moon. Check annually.
