lyder rigtigt, men det burde være hvert 10 sekund... Forklaringen er en temmelig kompliceret anordning hvor Lange 31 har et dobbelt fjerde hjul, hvoraf det ene uafhængigt aflader det enorme moment der er på optræksfjeder i 10 sek. intervaller. Uret enorme propertioner er heller modegimmick men ret og slet for at huse fjederen

When the one toothed wheel is unlocked it releases the full power of the mainspring, and rapidly jumps half a revolution only to be locked by the other pallet. As it is jumps, its pinon drives the bottom fourth wheel which winds the remontoir connected to it. The speed of advance is the relative power difference between the mainspring and the remontoir spring...which is a huge mismatch in power, thus the power train jumps once every 10 seconds. One can observe this in the movement, and also in the minute hand which, being attached to the second wheel, is released once every 10 seconds, and jumps once every 10 second block.

Der er således intet galt med uret, men en sideeffekt i deres konstruktion som tillader en denne ekstreme gangreserve i en manuel kaliber.
