Notes

 This particular movement went 2 times at the Geneva observatory in 1953 and 1966. The caliber 30T2 is one of the best manual wind movements produced. It is a simple design that won many of the observatory competitions year after year. The production of the caliber 30 mm designed by Henri Kneuss started in 1938 and ended in 1963
