I use one of those Atomic Wall clocks in the office by which all other clocks are set. Most other clocks are analog. Two are mechanical, one of those is a Howard Miller Grandfather clock and one is a Black Forest made Cocoo clock. I take great pride in adjusting the mechanicals and have gotten them down to being quite accurate to within a few seconds a week. I just received a 40 year anniversary clock from work. It is a floor clock but not a Grandfather clock like the company used to give. The electrical movement in it is the cheapest piece of China junk I have ever seen in a clock.
