Gold chronographs from the 1960s that exhibit such a well-rounded sporty design are quite rare.
The Seamaster 145.016 (and earlier 145.006) was designed to capture the excitement of racing, with a three-register chronograph radial dial layout. The 18k gold model usually had a distinctive black hand, although a few have been found with the orange one. There was also a rare, "exotic" racing dial version that featured a white chronograph seconds hand, while the hour and minute hands were red - a bold and unique design that didn't catch success in 1960s. The reference 145.016 was launched in 1968, powered by the new Omega caliber 861.
So, how this watch feels
I have photographed this model quite extensively by now. The dial has a so-called step-dial design. Also, it has a vertical brushing on the inner part of the dial, which means that depending on the angle of the light, the color of the dial can look different in tone.
