These 2 clocks are in perfect sync. I have noticed this about 2 months ago. The first time I saw these clocks were in perfect sync, I sat there for 50 minutes and listened to them, to make sure. And on todays quiet morning I was reminded of how these clocks are synchronized just by hearing them again. Today, I recorded a video because it is inevitable that someday one of these clocks will run out of battery and it will be over. These clocks are in the same room, and if these clocks were not in the same room to start with I would have never known. To clarify things, I did not try to make these clocks become synced in any way, it is just an extremely rare coincidence that when they were set exactly .5 seconds apart (for the second hand at least, the clocks don’t display the same time)
