Power Saving Feature
The battery is claimed to last about 54 months in normal conditions, but if you are not going to wear your watch for a while, the 5040.D has a power saving mechanism when the stem is pulled out stem (aka hacking function). Reduction of battery consumption approximately 70%. It is not advisable to leave the chronograph second hand running because it will drain the battery faster and put more wear and tear on the gears.
