1972 Spera Holiday Super-AutomaticSpera was a Swiss watch brand founded in Tramelan in 1919 and later operated as Spera S. A., with strong ties to the Vuilleumier family. Like many mid century Swiss makers, it did not survive the quartz crisis, but it left behind a small and intriguing body of watches. Its catalog included unusual and design led pieces such as jump hour models, divers, and travel time watches.
