When I like a watch so much, one might not be enough! 2012 was a year that Zenith surprised many of us with the introduction of the Zenith Pilot Montre d'Aéronef Type 20, a behemoth of a piece with the legendary caliber 5011. At its heart, a manually wound "observatory" pocket watch movement that was recorded by the Neuchâtel Observatory in 1967 as the most accurate chronometer it had ever tested. The movement, with a large 14mm balance wheel, coupled with a case and dial with cues from the original Zenith pilot watches from the very beginning of the 20th Century, stole my heart. The quality and finish of the movement was exceptional, as best described by fellow Purist: "It has a certain "vintage" feel to it, i.e. an airiness of the Côtes de Genève which seems to be applied by just a breath of air. Rarely seen these days!"
