EmailWHY WE LOVE IT? Because of its profile and shape: beautiful; because it is a industry-historic artefact: important; and because it is a 36'000bph-Automatic movement, that was a horological milestone in the late 1960s and early 1970s -- a technological manifest to precise and classic watchmaking and an answer to the upcoming electronics.
Made in Dec 1970 as indicated by the serialnumber stamped on the caseback and Citizens finest in 1970. The Citizen cal7230 has a seconds-hack feature and a daydate-mechanism; it is running flawless & precise on 5Hz -- the hibeat-frequency that is also used by Rolex' in its new cal7135 since 2025. Yes, high frequency-mechanicals were quite a thing more than 50y ago but fell victim to the upcoming electronics. First presented by Girard Perregaux in 1966 in their GyroMatic cal32A then used by many others (Ulysse Nardin, Seiko, Omega, Longines, Eterna etc) in their best mechanical-movements with its almost sweeping seconds-hand.
The Leopard SuperBeat 10 was approximately two times as expensive as the very fine adjusted Glorious Citizen (GC) and is one of the rarest vintage Citizen. Heavy solid-gold tonneau-shaped case (34mm without crown * 37.5mm lug-to-lug) with its original sunburst finish. The dial is of high quality and original in every aspect as well; beautiful preserved and a joy to look at, with its blacked minutes- & hours-hand and indexes (faceted) and the applied CITIZEN-logo.
