The Most Accurate Wristwatch in the World...Period

[BristolCavendish]

A tad cumbersome but it unquestionably meets the criteria.

If I got anything out of this somewhat ludicrous timekeeping example is that 99.9% of these advertised 'atomic' wristwatches = total BS.

As the author noted, a conventional quartz/atomic wristwatch 'resets' the movement at certain intervals via an RF transmission from Boulder, CO and if the optimum receiving conditions aren't present, they're nothing more than an ordinary quartz watch (with specialized capabilities). In other words, these so-called 'atomic' watches are not actually maintaining NIST time on a nano-second basis (although most users/wearers wouldn't notice any difference).

Besides, outside of scientists (or perhaps the truly OCD/anal-retentive), who would need daily watch accuracy down to a micro-second?

I don’t even check the accuracy of my mechanical watches. Let alone an atomic clock beast like that.

But I think this would look better on a gold chain around his neck.

Interesting. As Johnny Carson used to say: "I, uh, did not know that sir". "That's some wild stuff".

Remember Johnny?

That's why I like my Astron.

Very amusing. I wasn't expecting that.

Yes, but can you take it in the shower ?

You can wear most modern watches in a shower.......

But don't wave your arms around or bend down.

In addition to needing to read the signal, the transmitted time needs to be corrected for transmission delay to the physical location of the wrist watch. And, there is a temporal difference caused by the physical altitude of the watch (time dilation). Are these home atomic clocks accounting for these errors as well?

I found the most accurate watch in the world is the one my boss planted in my head...NOW!
