The extra-flat Quartz watch reaches chronometer rating BF 347
Once again, WITTNAUER of Geneva has made an important contribution to time measurement. Its new ringa of extraflat models for gentlemen and ladies is the first to reach Chronometer rating with ETA Flatline II Quartz movements. (thickness only 2,5 mm) This is the highest distinction the C.O.S.C. (Swiss Official Chronometer-Testing Institution) can award. It signals the achievements which in 1976 already had obtained the first Chronometer certificates for 44 LEO Quartz digital watches. The historic time-piece is on show at the International Watch Museum in La Chaux-de-Fonds
