How else will you know exactly how inaccurate the watch is?

But do note that some mechanical watches are accurate enough to not wander quite that quickly, as seen here: https://thetruthaboutwatches.com/2021/06/watch-accuracy-rolex-vs-casio/

Guilty as charged.

But the old “entertainment center” killed all that. Just as jeweler watch displays tend to set all the watches to the same static time so, you know, they don’t all look like they’re all keeping different time, once televisions and VCR’s made it so two or more different digital time displays were visible together, this error needed correction to avoid being a constant annoyance. Any discrepancy between them was unbearable.

Once I had a few watches, it became a thing to note that every month or so the minutes were out of agreement and to align them to some reference. But then the damned cellular telephones got second displays. Suddenly everyone had a seemingly indisputable uniform time always at hand, and there was no debate about whether one was actually late for the meeting or not. Exact minute and seconds mattered once again.

Of course the synchronization takes at least a couple minutes for each time piece, so I still only do it every few weeks. But then I’m a quartz fan, so I don’t need to do it much more. But I recently discovered that the reference time on the computer clock and the cell phone were many seconds apart. My world was shattered. What was real anymore?

I was going to goof on this Hodinky app and the tenths of a second. But then I remembered this issue of the hourly chime of my Casio and cell phone app slowly diverging from unison to a full second or more apart. I feel I’m setting myself up for unhappiness with this. The price of the joy of seeing a bunch of watches running with the second hands all parallel to one another is getting perturbed when entropy inevitably disrupts this. But at least I know that others have this mania.
