Notes

 This Chronometer was submitted successively at the Geneva observatory where it obtained a bulletin de marche for first class category from November 1909 and then immediately submitted to the National Physical laboratory in Richmond where it obtained its Kew A certificate. Amazingly, all the documentation pertaining to these trials have been kept.
