what an impressive watch this Zenith Pilot Montre d’Aéronef Type 20 is.

With its legendary 5011K hand-wound movement.
This movement was considered the most accurate in the world in 1967 and received over 300 awards and prizes.
COSC-certified and tested by Neuchatel Observatory it only existed in the Zenith archives with 250 pieces and was specially switched into the Montre d’Aéronef Type 20 watch model.
In 2012 (year of publication) it won the international mechanical watch of the year 2012 award.
And with a diameter of 57mm it is - ALMOST !! - wearable. Hahahahaha
Visited my bank safe today to switch some of my watches from autumn/winter to spring/summer and so had the chance to admire this leviathan again.
Cheers
