In 1969, Omega commissioned Anglo-Italian jewellery designer Andrew Grima to design a collection of watches - the 'About Time' collection. The collection was released in 1970 at Goldsmiths Hall in London to great acclaim. Signature Grima elements include the use of textured gold, unconventional stones and powerful sculptural design. Based on the success of this range, Omega later produced their own designs inspired by Andrew Grima’s collection.
