★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 the Shokosha (CITIZEN) pieces are ★quite rare! ★My personal favorite is the "chronometer Revival" naming, which was a pioneering name for the Chronomaster Revival later sold by the prestigious Zenith! ★In the operational check before listing, it was running at a usable level, even though it's a mechanical watch from over 90 years ago! 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 level of wear to be a ★badge of honor★ for a vintage piece! ★For the true enthusiast★ Free shipping!
