Thank you for the answer! I wanted to know how many seconds does the watch lost per day? Many thanks

off all five positions is d=8 sec / day, though ... Just a test result of one watch, but normally it can be seen as a representative result. Regards Moritz

The behaviour of the watch is influenced by so many parameters that you can't define a precise amount, just thresholds. If my memory is right, the precision range of a Lange watch is -3 /+7. But you can at least expect a precision range within the COSC on... 

But in reality it depends on the individual example as well as the temerature, humidity, position, etc. What I hate most about watches is when it loses second. I would rather ones that gains +5 a day, so that it is easy to re-adjust. No matter. If your La...
