Solid and chunky to withstand the weather, this slate sundial is not just useful but makes a beautiful accent piece for the garden. No batteries needed and it'll go on working for years and years - the original eco-friendly clock. Place it on a flat surface in direct sunlight, with the pointer (gnomon) facing north. Pick a time on the hour so you can make sure the shadow falls on the current time. If it’s a little out adjust it until it’s accurate, then as long as you don’t move the sundial it should keep time quite reliably. Measurements: L24.5cm x D24.5cm x H16.5cm Weight 2.5kg #gardencollection
