This Zenith AutoSport dates to the 1960s and carries the energetic identity signalled by its '28800' designation. The case and dial express the sport-minded design language of the era, while the movement is Zenith’s Cal. 2562 PC — an automatic calibre built to run at a higher beat. That dependable, higher-frequency construction offers a crisp, modern feel to the seconds hand and daily timekeeping. For a contemporary collector, this model represents a direct link to mid-century sporty design married to technical ambition, appealing to those who value mechanical refinement and period character.
