Needless to say, these rare iterations are lusted after by Zenith cognoscenti, and for its latest release, the brand has created a stunningly faithful revival of this elusive vintage reference. Only one model in this original period, the El Primero A3817, ever carried both the tonneau case and the tricolor dial, and that watch had a production run of only 1000 units for a brief period in 1971. Many of these early iterations of the El Primero either sport the compact, angular tonneau case like the A384 and A385 lines, or these watches use a more traditional round case design with the line’s instantly recognizable overlapping tricolor chronograph subdials, like the A386 series. When discussing the first generation of Zenith’s legendary El Primero automatic chronograph series in the late ‘60s and early ‘70s, most models fall into one of two camps.
