powder coated time and tide clock - with hours remaining until high and low water. Synchronised to the moon's daily cycle, the combination time and tide clock gives you an innovative and convenient guide to tides, whilst also providing conventional time keeping. This design also provides an indication of how many hours remain until high or low water. The black conventional clock hands work quite independently from the tide hand and can be adjusted using the small fly wheel on the back of the movement. The tide hand can be adjusted using the larger wheel, again found on the back of the movement. 195mm in diameter. Wall mounted.
