Information of Ulysse Nardin about this chronometer: “About the closing lid number we don’t have information. Usually the wooden case has the same number as the movement, but sometimes they deviate. The electric device was to make this chronometer like a “mother clock”. Once connected to another device it could show 1/100th of seconds!”
