clepsydra Wrote:Hi Adrian et al,Correct me if I am wrong. The terms - chronometer and half chronometer - mean that, at one given time, the movements in the pws with that designation in the case or the dial, were tested and fine tuned to a high degree of accuracy, under test conditions. It did not mean that those movements were manufactured with higher quality parts or assembled with extra care, to earn that designation. It did not guarantee the movement would maintain that performance once faced with daily use outside the factory, or the testing agency.Is there a record of which calibers had (selected) movements that earned the label chronometer or half chronometer?
