    I posted a thread earlier with power measurements of a Kundo ATO clock.

    I've now done this test with a Haller ATO and a Takane quartz movement.
    Battery life was calculated using 2.5Ah capacity for the AA battery.

    The Kundo is the best so far. 53 uA of current used.

    The Haller uses 135 uA. About 2.1 years of battery life.

    The Takane uses 180 uA. About 1.5 years of batery life.

    It's interesting that the most modern clock also uses the most power. It does have one advantage. It's far more accurate.
