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 and of course the well known TvB wristwatch: http://www.leapsecond.com/pages/atomic-bill/ 73s Achim, DH2VA ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
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. You will see 60Hz/120Hz buzz in the background but the second hand stepping impulses will clearly show as a sharp impulse every second. Of course a small electret microphone can pick up the sonic impulse too and will also be useful for purely mechanical watches. Broadly I’ve found cheapie quartz watches to be way more accurate than a minute a month. In the past I’ve marveled here about my cars clock which drifts less than a minute every 6 months (DST change reset interval) despite being in a very adverse temperature range.

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 environment. If the watch is off temperature vs the assumptions, it will not keep good time. Some numbers: 10 seconds a month is 3.8 ppm 120 seconds a month is 46 ppm The temperature curve is parabolic so *usually* temperature will result in a slow watch. If the “target” set point is 10 seconds fast, you would need to be right at 50 ppm off to loose two minutes a month. If you take a look a the previous numbers on trim range on the trimmer. A trimmer that will do +/- 25 ppm is “adequate” for setting the watch in production. It’s not good enough (by a factor of 2) to take care of a 2 minute / month timing error. Just for the record, I don’t think I have *ever* owned a quartz watch that was off by more than a 15 seconds per month. I’ve owned cheap ones and expensive ones. They all have done pretty well. The fancy ones *have* done better ….

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 probably not much of a problem; I once tried seeing the 32kHz signal in the watch by capacitive coupling to the face, and could detect the signal. I just tried a token attempt on my current watch and failed, but it was a crude, unshielded attempt by merely laying a 'scope probe against the watch face. I was being severely jammed by the local 1230 kHz AM station. Anyway, the idea is to observe the signal's phase drift while triggering the 'scope from a trusted 1PPS source. So now all that's needed is an alternate way for trimming the watch's frequency without opening the case. There must be a way...

Trimmer caps to set watch crystals are problematic. They are a source of error as well as a set mechanism. You bump this or that and the trimmer moves. They also cost money to buy and install properly (no flux in-between the plates …). Once that is all done you need a way to set them in the factory. Back in the day, yes, we hat line workers who did that sort of thing. We also sold the crystal in the watch module (not the whole module) for $2 once upon a time. How close do you want to set it? In our case, the set was supposed to be < 0.5 ppm of the target. Ideally you needed a design that would do a small fraction of a ppm in a typical situation. If the trimmer is a normal device, you get about 120 degrees of travel for the useful part of the tuning curve. A tune range of 30 ppm for the crystal and another 20 ppm for the other parts would not be unusual. Even taking the 0.5 ppm number, you are into 120 / 100 = 1.2 degrees sort of set on that little trimmer. Bottom line: They went away because they weren’t good enough and they were to expensive ….

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 its ability to coast at a known rate between checks against WWV, which opportunities are not always available when one wants, due to propagation issues. Whatever happened to the quartz watches with trimmer capacitors for setting the rate? And radio controlled? No way! The process is to delicate and marginal to rely upon. Give me a good stable free-running watch any day. I don't like the solar watch concept mainly because one sometimes has to go for weeks without an opportunity to expose his watch to direct sunlight (or some indoor equivalent) for the requisite period of several hours. Yesterday I was reading the manual for the Citizen ECO series, and that thing requires far too much effort and complication to keep it working and on time. A good watch must simply work, with no maintenance beyond occasional battery replacements (and possible gland replacement at battery-change time), and accurately enough that the time need never be reset between battery replacements. I use an old quartz diving watch I bought just under 10 years ago, (brand no longer distinguishable), which has never drifted more than about 30 sec (usually less) between battery replacements, and I never take it off between batteries except when compelled to do so at TSA checkpoints. Aside from its LCD's failing I'd be happy to use if forever, but it's getting awfully hard to read these days.

The doors on trains in the UK lock up to 30 s before the train is due to leave. It is most frustrating to arrive at a platform, with the train stationary, but no way to get in. I would estimate that about 20 seconds is good enough for making a decision about just how fast one has to run for a train. Buying tickets for events like Wimbledon tennis in the UK can demand one attempts at the right time, as tickets become available and sold out very quickly. But one would be using a computer to purchase them, so I don't think that comes under the requirements of a wrist watch.

For non-formal, day-to-day wear, I've been partial to Casio G-Shock watches for a long time. They're rugged, reliable, and have the basic features one might want: stopwatch, countdown timer, a few user-settable alarms, etc. without too many bells and whistles. Watches with "Multi-Band 6" have long wave time signal receiving capability and can receive signals from WWVB, MSF, DCF77, and transmitters in China and Japan. They also make watches that have GPS receivers, and hybrid GPS and long wave receivers for redundancy. I've worn a GWM850-1, which is a Multi-Band 6 watch, for a long time and it's served me well. Unfortunately, Casio doesn't make that specific model anymore, but there's lots of other similar models available. Mine tries to set itself every night starting at midnight and trying again hourly until it either succeeds at setting the time or it fails after 4:00am. It also charges its internal battery from a solar panel formed into the watch face, so one never (modulo the battery eventually degrading) needs to change it. I've found that even with liberal use of the EL backlight, the battery never gets below the "medium" level during winter when the watch rarely sees the sun, and then fully charges up again in springtime.

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. http://www.citizenwatch-global.com/support/pdf/u600/e.pdf The link to the manual is above. Good luck.

Re: [time-nuts] Need a Watch Recommendation
I think what makes the IWatch unique is it has an option that makes it a standalone cell phone. With this new option it no longer need to be in proximity of you IPhone. You leave the IPhone at home and have a fully function cell phone on your wrist. The only hitch is they will not let you active a watch separately, it must be tied to you IPhone number. Garmin also make some nice sport watches that a fully functional GPS receivers. Everything but a one PPS and 10MHz output.

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 right now doing a fantastic job of timing the eggs I'm boiling for my lunch.

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. http://www.radiocontrolledclock.com/ateuransporw4.html On Mon, Mar 5, 2018 at 4:19 PM, Larry McDavid wrote: > I really don't want a conductive metal-case watch on my arm.

Re: [time-nuts] Need a Watch Recommendation
For those of us whose time-nuttery extends into the fascinating world of mechanical watches and clocks, the kind of accuracy usually discussed here is not only impossible but essentially irrelevant (quelle horreur!). Our interest is in the beauty and elegance of micromechanical devices that have evolved over centuries. When I look down at one of the 25 or so wristwatches in my small collection or up at the ten wall and floor clocks in my home, I am seeing far more than merely the time. If all I want is the time, I can always glance at my phone or go to the basement and fiddle with one or another of the electronic devices there. My oldest watch, a Waltham Model 57, has been running continuously for 150 years and still keeps time within a minute per day. Horology is about so much more than crystals and resonances and Allen deviations.

Hi Bill... My Rolex GMT Master was stolen back in '75, so no luck on that. Rolex is a bit pricey for my needs. My Seiko CQ001M, one of the first Seiko Digitals, was amazing.

[time-nuts] Need a Watch Recommendation
Hello Time Nuts... After 6 years of no troubles, in sync with WWV any hour of the day, flawless transfer between standard and daylight time my Stauer Titanium Atomic wristwatch bite the dust a year ago. Since then, Stauer has sent me three replacements, each with some type of problem. So it looks as if I am in need of a new wristwatch, which will give me some kind of time accuracy. So, Time Nuts... any suggestions or recommendations?
