Gerd-Rüdiger Lang founded Chronoswiss in Munich in 1983 as a watchmaking atelier specialising in mechanical chronographs at a time when the quartz crisis had gutted most of the Swiss industry. Lang had trained at the German watchmaking school in Pforzheim and worked at Heuer in Bienne, and he had amassed a private collection of defunct-maker movements (Valjoux, Venus) that became the parts reservoir for Chronoswiss's early production. In 1987 the brand launched the Regulator Automatic (Ref. CH1223) - the first serial-production mechanical wristwatch with a regulator dial layout (separate large-minute hand with subsidiary hours and seconds dials). The regulator had existed only as an observatory reference-clock style before; putting it on the wrist became Chronoswiss's defining contribution to modern horology.
Through the 1990s and 2000s Chronoswiss built a catalogue of classical round complicated watches - regulators in every size, chronographs (Kairos, Pacific), dual-time pieces (Timemaster GMT), and the Sirius skeletonised regulator. The coin-edge case with knurled bezel and fluted crown became the visual signature across the entire collection. Lang also developed the distinctive cadrature style featuring screwed bezel, prominent onion crown, and lug horns. Until 2012 production remained entirely in Munich, with Swiss movements (Valjoux, Enicar, Enicar-derived) retrofitted to Chronoswiss specifications.
In 2012 German-Swiss entrepreneurs Oliver and Eva Ebstein acquired Chronoswiss and moved its headquarters to Lucerne, Switzerland - the brand becoming fully Swiss-produced for the first time. The Ebsteins modernised the aesthetic with the Flying Regulator Open Gear (2017) and Flying Grand Regulator lines, introducing more contemporary colour palettes (purple, turquoise, green) while retaining the coin-edge case signature. Open Gear references expose the gear train and regulator's motion-work through a skeletonised dial. Production is small (estimated ~2,500-3,000 pieces per year), with retail ranging from ~CHF 6,500 (Delphis automatic) to ~CHF 20,000+ (Flying Grand Regulator Tourbillon).
