Re: [time-nuts] Need a Watch Recommendation

Hello Dave, being 'time-nuts', it is of course to know the time of day to the nanosecond! That said, I truly believe there are only two wristwatches out there for the serious time-nutter: https://www.kickstarter.com/projects/846511652/the-worlds-first-true-atomic-wristwatch-the-cesium/updates

Re: [time-nuts] Need a Watch Recommendation

Dana, the magnetic impulse of a quartz watch stepping the second hand forward is easily picked up by an unshielded coil. Wind a couple hundred turns of magnet wire around a bottle cap and hold near the watch face. Plug into the microphone input of a PC and run audacity to record the waveform.

Re: [time-nuts] Need a Watch Recommendation

Hi The most common way to pull the 32KHz signal off of a watch is via a tuned microphone. At least that’s the way we did it in production. A watch crystal *can* (but usually doesn’t) move > 100 PPM with temperature. When things are set up, assumptions are made about “your” temperature

Re: [time-nuts] Need a Watch Recommendation

Most of the quartz watches I've owned were off by about 1-2 minutes per month, which I consider inexcusable. Agreed, the mechanical trimmer is rather problematical, but I'd sure like to see *something *that the sophisticated user can tweak at home. Measurement of the current rate error is

Re: [time-nuts] Need a Watch Recommendation

I concur with Bill. And even if one keeps tabs on the current watch error, as is the usual practice by celestial navigators, once that error reaches or exceeds more than a minute the process frankly gets more clumsy and error prone. And if a watch drifts in time very rapidly, one loses faith in

Re: [time-nuts] Need a Watch Recommendation

Don, I am very pleased with the performance of my CITIZEN Eco-Drive SKYHAWK. It can receive WWVB (USA), JJY (Japan), or DCF77 (Germany). I am convinced it is accurate to within 1 second at all times. It is a 'Blue Angels' watch, part of the NaviHawk series I think.

Lots of folks have chimed in on this thread, but I will just add that the Apple watch is an NTP client. I’m extremely happy with mine, but the reasons I am are far, far wider than its accuracy (which I can only judge by eye, which is an extraordinary low bar for a Time Nut). > On Mar 4, 2018,

Re: [time-nuts] Need a Watch Recommendation

And that is just my point--well, part of it, anyway--ultra-precise measurement of time is profoundly important, and rightly the primary focus of this group. But for the wrist, very, very few of us need pin-point accuracy--though many seem to perceive that we do. My Tissot mechanical chronograph is

Re: [time-nuts] Need a Watch Recommendation

Eurochron (I believe they're low-end brand of Junghams) make a plastic DCF77 watch. 'Plastic' doesn't do it justice - although the one I had eventually wore away, it was attractive and well made and lasted for several years. I think this is the WWVB equivalent.

Re: [time-nuts] Need a Watch Recommendation

I really don't want a conductive metal-case watch on my arm. What I do want is a light-weight, thin watch with day, date and analog display with sweep second hand. Not digital... Ok, that may be old-fashioned but it suits me. I've never found a suitable wwvb watch. So, I opt for an

Re: [time-nuts] Need a Watch Recommendation

Even my pre civil war pocket watches should be good enough for your needs. Better than a minute/day. But for some (many) time-nuts it's about wants, not needs. My clocks and watches that can be heard across the room qualify me as old school time nut. (My DOB qualifies me as just plain old.)

I wore a Casio "Atomic" watch and it set itself reliably for many years until very recently. They are still available.  I've replaced it with a Seiko Solar "Radio" watch which I understand has a better wwvb receiver in it. Haven't worn it yet so I'm not sure how it will perform but I've heard
