So speaking of Zenith, here it is. Just picked up my first vintage watch, an El Primero Chronograph ref A787 (circa '71-'72). While not as famous as the 1969 A386 & A384 duo, it shares the same Cal 3019 PHC movement and the dial has similar design aesthetics. Only 1500 made, but relatively affordable compared to its iconic siblings. It's quite comfortable to wear and I love how slim it is, only 12mm thick including the domed plexi crystal.
