Rightfully, Zenith started with what is simply its most iconic watch – the A386 – which I have always felt, from a design standpoint, nicely bridged the late ’60s and early ’70s. It’s a classically round chronograph with pump pushers and a dial with a flamboyant tri-color palate. Also in 1969, Zenith debuted a second case shape, its angled tonneau, which feels much more anticipatory of the 1970s that were to come. This is the tonneau-shaped watchcase seen in the A384, and A385, and later in the A3817 and A3818 “Cover Girl.” According to Manfred Rössler’s book Zenith: Swiss Watch Manufacture Since 1865, there were 2,600 examples of the A384 made from 1969 to 1971. Just looking at this case shape, you can see how it would inspire Zenith’s Defy line.
