JUSTIME Tide Clock, 21.6 cm (8.5 Inch) Tidal Wall Clock with Water-Resistant Plastic Case, Colourful High & Low Tide Coastal Home Décor for UK & Atlantic Coastlines (TT019 Blue)

COASTAL COMPANION: A 21.6 cm (8.5") tide clock for anglers, surfers, sailors, sea swimmers, coastal homeowners and anyone who likes to keep an eye on the tides — see at a glance whether the tide is coming in or going out, and roughly how long until the next high or low water.

SUITS UK & ATLANTIC COASTS: Designed for coastlines with regular twice-daily (semi-diurnal) tides, which covers most of the UK, Ireland and the Atlantic coast of Europe. It tracks the average lunar tidal cycle, so simply set it once against your local tide table — and reset occasionally (a full or new moon makes an easy reminder) to keep it spot on.

DURABLE, WATER-RESISTANT BUILD: A quality ABS plastic case with a water-resistant rear cover, finished with clear, colourful high-tide and low-tide graphics. The locking rear cover and 3-point secure screw mount fix it firmly to a wall at home, or hold it steady aboard a boat.

SIZE & BATTERY: Approximately 21.6 cm (8.5") in diameter and 4 cm (1.6") deep, for indoor use. Runs on one AA battery (not included). A carbon-zinc battery is recommended for steady running and a longer service life.

A THOUGHTFUL GIFT: Stuck for an original present? A tide clock makes a lovely gift for sailors, surfers, sea swimmers and anyone who loves the coast — ideal for birthdays, Mother's Day, Father's Day, Christmas or a seaside housewarming.
