★Rare! This is a piece from pre-war Japan where Shokosha (CITIZEN) sold a revival of a Swiss.Camel chronometer in their own case! ★Back then (pre-war), Hattori Tokeiten (Seikosha) and Yoshida Tokei (Orient) also sold Swiss movements in their own cases, but this Shokosha (CITIZEN) piece is ★quite rare! ★My personal favorite is the chronometer Revival naming, which is a pioneering naming convention that later inspired the Chronomaster Revival sold by the prestigious Zenith! ★In the operational check before listing, it was running at a level suitable for everyday use, despite being a mechanical watch over 90 years old! Miraculous! ★The exterior shows signs of wear and tear, with scratches and aging, as it is over 90 years old, but I personally consider this to be a ★badge of honor★ for a vintage piece! ★For the discerning collector★ Free shipping!
