Preloved minimalist wall clock by IKEA space age yellow, black and steel

We are unsure of the production year for this large IKEA wall clock. Named 'Dassigt' on the back but doesn't match more common Dassigt clocks when researching - quite a rare item. Bright yellow face with simple black hands and no numbers. In preloved condition with some light signs of use such as the odd surface mark, but no dents, dings or breaks. Working condition with fairly quiet tick. Approx diameter 30cm. 5cm deep.
