Reference 176.007 is the poster child of the 1040 family. It is the most common, most beloved, and most recognizable. It’s barrel case came in either steel, 20-micron gold plate, or 18k gold with brushed sunburst finish from the crystal to the edges. It came with either a bracelet or strap.
This is easily the most common reference of the family and can be found in more variants with more dials than other references. The 007 was depicted in ads and catalogs every year from 1972 through 1976 with at least 5 different dials. Steel watches had dials in blue (two styles) and silver, while gold-plated watches came with either gold or brown dials. There was a solid gold version made, but in few numbers. A gold 176.007 was gifted by Omega to Albert Piguet when he retired from Lemania and is currently on display at the Omega Museum
