Ahead of its time when it
was launched 50 years ago,
Zenith’s famous 36,000vph
El Primero calibre celebrates
its first half century with
what is being billed as
an optimisation of “latest
technologies and perfor-
mance algorithms” (always
a bit suspicious of algorithms
but we will let that pass).
What’s new is improved
power reserve (60 hours); an
easily read tenth-of-a-second
display on a scale with 100
graduations; a balance-stop
device; a reversal of the
crown sequence (the original
was counterintuitive);
improved column wheel;
and an optimised lateral
clutch that now includes two
intermediate wheels—about
time too. In other words; all
good for the next 50 years.
