·Accuracy !!
Sometimes, we tend to forget to give a compliment to the accuracy of Constellations. The fact is most of the time when I bought an old (40 to 60 years old) Constellation, it always runs accurately, +/- 10 seconds /day before service by watchmaker. A true and tough chronometer grade movements! From 1950s cal.352, 354 and 501 to 1960s cal. 561 all are excellent movements!
