Watches, Automatic Vs Mechanical

[#13535736]

I know quartz watches are slimmer, lighter, more robust and accurate.

Having said all that, I've recently developed an itch for an automatic watch, probably a field watch.

I know, if field watches were invented today, they'd be quartz and the originals were mechanical not automatic so an auto is perhaps the least genuine option for a field watch.

Given that mechanical/automatic watches are less accurate the time will need correcting frequently. So while doing that, I might as well wind a manual, is it worth the extra for an automatic?

Or is it a case of this being a heart purchase and not a head one so just get the auto that started this query?

some people find winding it all the time a pain in the arse, some people enjoy the routine, ie with their daily coffee

If a watch gains say 10 sec a day in reality that means you correct it maybe once every week or two. 

If I want to be more accurate than a couple of minutes, I check my phone. And I use a digital not analog display. 

There are good reasons for mechanical, auto or other watches, but accuracy really isn’t one of them these days.

My main watch is 64 years old and is manual. If you are buying a vintage watch then a non date takes away some of the faff because they are often not a quick set type so need a lot of crown spinning to set the date. Only anppli if you don’t wear it for days or weeks. Other than that manual watches are fine, I wind mine around 9pm.

If you are looking at new then the Hamilton Murph 38mm is well worth considering, it is automatic

I almost always wear an auto of one brand or another and find that they are generally accurate enough that I don't find myself adjusting them for minor discrepancies that often, if at all. I may have to set them if I've not worn them for a while but no more than this. My main watch can be on my wrist for weeks and I'll not be adjusting it.

Quartz watches aren’t as accurate as you might imagine, most of my watches are mechanical, one is a manual wind, and my TAG Heuer ‘NightDiver’ is a quartz, plus I’ve got several Casio watches that can and will lose or gain a certain amount, and a mechanical watch, provided the movement is hackable, is very easy to adjust.

As you might only be having to reset/adjust once a week or maybe even every couple of weeks, depending on how fussy you are, an automatic is probably the best option, because as long as you’re wearing it, it’ll keep running without you even thinking about it.

From my own experience with my Yema Rallygraf, which is around fifty years old, I find myself absentmindedly winding it without even thinking about it, but that won’t last more than 24 hours on a winding.

Automatic mechanical all the way.

Oh, and a quartz watch will have to go into a shop to have the battery replaced, because most have a screw caseback and, if they have any sort of decent water-resistance, like 200m, you certainly won’t be able to do it yourself!

An automatic will only need opening for a service every ten or so years, many go a lot longer than that!

And he said

I've got a few watches, they are all either mechanical or automatic, they all keep decent time.

I wear a Seiko 5, it’s bashed, scratched and scraped. Being an engineer I appreciate its a little marvel of modern manufacturing that happily puts up with its abuse. I wouldn’t deliberately seek out a manual wound watch over an auto - that just feels a retrograde step too far.

I hve a Seiko Kinetic, which is a fantastic watch. It is incredibly accurate and the charge lasts for ages (powered by wrist movement). I bought it specifically so it wouldn’t need a battery replacement - thus losing its waterproofness. I also have a lovely Tissot, which was much more expensive, but is significantly less accurate, and the charge doesnt last as long.

I have two Seiko 5s (well one 5 and one diver that has the same 7S26 movement). They are absolute works of utilitarian engineering art. I love 'em.

The 3 main advantages of a manual movement are cost, thinness, and aesthetics.

My "nice" watch (this being a relative claim on STW I know) is a Citizen Eco Drive.  Aside from specialist devices it's easily the best watch I've ever owned if your primary requirement is "telling the time".

It keeps perfect time, it has a perpetual calendar, and is solar powered so zero maintenance aside from changing it daylight savings.  If you keep it in a coal mine (or for some bizarre reason, a drawer) a charged battery is good for about three days before needing a light source again.

I don't know what a "field watch" is, but if I had to go back to a manual winder again it'd never get used.

A watch gaining a minute a week isn't fit for purpose, that's ludicrous.  I'd send it for repair or ebay it.  (Actually, I'd probably do neither of those things, I'd most likely sling it in a drawer and forget about it.)

COSC certification, which only ~5% of Swiss watches produced meet, allows up to +6 seconds per day, or +42 seconds per week. A minute per week (or +9s/day) is in no way "ludicrous" and falls well within acceptable timekeeping for a mechanical watch.

A minute per week (or +9s/day) is in no way junk and falls well within acceptable timekeeping for a mechanical watch. 

Conclusion: mechanical watches are junk by design?

The specs for my Citizen list accuracy to within +/- 15 seconds a month (in practice mine is much less than that).  Worst case scenario that's 1.5 minutes every six months, and every six months is when I accurately re-set the time using an NTP source during the GMT/BST switch.  1.5 minutes is about as far as I'd want a watch to ever be incorrect by.

In that same timescale your minute/week timepieces are half an hour out and your certified best 5% of all Swiss watches are wrong by 18 minutes.  I fear that our definitions of "acceptable timekeeping" may differ somewhat. 😁

Very loosely, an automatic is probably a better bet. As everyone points out, with most modern auto watches, correcting the time is something you can do when you think about it or when it bugs you; but winding a manual watch is something you have to do religiously. 

If the timekeeping bothers you, you could go for a mechanical quartz type (eg Seiko Spring Drive); otherwise you'll be grand

After years of various smart watches,from Samsung, Fitbit Google and Motorola which variously needed charged, updated, synchonised to my phone etc, and all of which broke down inexplicably I have also opted for a citizen Eco drive it's been flawless since I got it 18months ago and doesn't need wound up. 

Perfect....

Definitely. I'm not telling people I'll meet them at the local at 19:22. I work in 15 minute segments, 5 minutes if I absolutely need to, so if my watch needs nudging forward a minute twice a month I'm happy (as are Contrôle officiel suisse des Chronomètres) that it's capable of "acceptable timekeeping".

If your need for a watch is purely to tell the time, then you buy a Casio F91. They're piss cheap and work perfectly.

If you're buy anything more than that, it's because you're buying it because of how it looks (it's jewellery basically) and/or how much it costs and/or how it works and/or how accurate it is, and you're making a judgment balance between those four factors.

For me, I'll buy/use a mechanical watch, and take the (to me) trivial hit on timekeeping, because I think a mechanical watch mechanism, especially an automatic one, is an inherently brilliant thing.

Manual? Classic, but something of an affectation. Automatic, nice but even fancy ones drift with their timekeeping. I now rely on my Elliot Brown quartz ‘Singletrack’ Horton. 

However, this is also influenced by the fact that I can no longer hear its quartz ‘tick’ as well as its excellent timekeeping and very reasonable battery life and battery replacement cost.

A watch gaining a minute a week isn't fit for purpose, that's ludicrous.  I'd send it for repair or ebay it.  

The reality is, though, that the specifications are +/- per day, unless a watch movement is really worn or dirty, the deviation is more likely to be a minute or so every couple of weeks, maybe even months. Even if one of my watches was gaining a minute or so a week, I wouldn’t be too bothered, there’s nothing I do that needs that level of accuracy anyway - I might notice if it’s gone more than a couple of minutes in a month. Dead easy to reset with a hackable movement, takes a few seconds…

And just to add, as this subject had come up, I decided to dig my quartz TAG out. I haven’t worn it in ages, probably two or three years, so the time was a bit out, what with clocks changing, etc, and the date obviously was way out, but it’s running fine, and that is one advantage over an automatic or a manual; it will be still running, but just not showing the time correctly if clock changes had taken place.

It’s showing it’s age a bit, the black PVD coating is pretty worn, the bracelet is even worse, and the lumed face, hands and markers are nothing compared to modern Lumibrite or Super Luminova.

It does also look a bit small compared to my other dive watches. 🤷🏼‍♂️

The reality is, though, that when I reset mine for BST recently it was out by less than a minute.

I had one.  I would agree that they're piss cheap and work, though "perfectly" is a stretch.  I don't recall it being the greatest timekeeper (though it was a long time ago now), the backlight served no purpose other than to drain the battery, and the buttons quickly wore out.

You can buy modern movements for them these days as a direct replacement.  Gotta say, I'm tempted.

This is the vinyl argument.

I don't disagree that it would be a lovely thing, but taking a "trivial hit on timekeeping" ON A WATCH is just barmy to me.  Do you also have an iPhone Pro that doesn't make phone calls very well?  A Lamborghini that starts most of the time?

We'll have to agree to differ here I fear. 😁

Like I say, 8 have a couple of nice quartz watches that keep time perfectly well.

This is just an itch to own a miniature mechanical marvel on my wrist that, while it will keep adequate time, it probably won't do it as well as the quartz.

Logic then says buy the quartz, but I already have quartz, therefore no need to buy a new watch...

Unless I just want mechanical/automatic for the sake of having mechanical/automatic.

Don't "need" a watch at all. I carry my phone more than I wear a watch. That tells time pretty well

@Cougar - for what it’s worth I have one COSC watch and the certificate told me what the inaccuracy was in each orientation. By laying it in a particular way when I took it off each night I got it to about a second a month. 
But accuracy is overrated when you’re carrying a phone most of the time anyway. 
A watch is slightly functional jewellery really.

I too have a Citizen EcoDrive that tells the time with remarkable precision. 
That said, I've just treated myself to a Redwood Monsoon Stealth. A clean face, solar powered and no date - so it just tells the time.

Automatic is fine but solar power is fine too. Plenty to choose from Seiko,Lorus or Citizen)

If you are as bothered as me then get a Casio Tough Solar with international atomic time or radio-controlled time.

Agreed - i went through a PROPER phase of watching youtube videos of mechanical watch movements, repairs, and rebuilds.

If you like engineering, mechanical watches are teenty tiny scale engineering incredibleness!!

I think it is clear some people have a different relationship to time than others. With my mechanical watch I tend to set it roughly every couple of weeks when I have to move it forward a minute.

But when it comes to my use of time. If you ask me what time it is and my watch says 5:53 I will reply five to six. If I have to be somewhere I am generally a little early, I don't like to be rushed. One minute either way on a watch is fine by me.

I have had it since 1989 and I am quite attached to it.

The thing is though, Cougar, who genuinely needs a watch with that degree of accuracy? I check my watch for the time, but honestly so long as the time is somewhere around correct, like within a couple of minutes or so, I really don’t think it’s important. If I want the time to the second, I have my phone for that, but I’ll take a quick glance and the time could be somewhere between five and ten past the hour, which is quite good enough.

It’s only if the time is crucial, like catching a train or something that it becomes more important. YMMV.

Autistic people?  Knowing that I have a clock on my wrist which is probably wrong would drive me insane.

That aside though, eh, I don't know.  Why would you not want an accurate time?  I want to watch my favourite show but I'm really busy.  Have I got time to feed the cats or should I wait for the first ad break?  I sit down with my tea at 7pm after getting as much stuff done as I can and I've missed the first few minutes because my watch is slow.  Or I'm meeting someone in town at lunch, I'm only a minute's walk away but I actually get there five minutes early because my watch is fast and now I have to stand in the pissing rain doing absolutely nothing.

I'm punctual, in the literal sense.  We've discussed this on STW before.  I'm very rarely late, but I hate waiting, it's an abject waste of time for everyone.  If you want me somewhere at 6pm, I'll be there at 5:59.  If you're expecting me ten minutes early then you need to communicate that.

Have you never asked "how are we doing for time?"  You must have more of it than me.

I wear a G-shock most of the time. It has one of those radio beacon time setting magic thingies.. absolutely accurate and if I don’t have the phone on me then I use it so set my manual/automatic watches … which I wear because they are nice objects ..

So you're permanently busying yourself between each scheduled activity? And only leave just enough time between each activity and the next to make any necessary travel? I've got to say, that sounds exhausting

This is a heart over head issue. buy the one you like. 

Ive got a number of watches. quartz, mechanical and automatic. 

You are about to enter a realm of absolute nonsense (imo) if you start looking at specs. Not only do you get varying degrees of accuracy but some are only measured if your not wearing it, in specific orientations of the moon or after being rubbed on a virgins kneecap. Its absolute tosh. A mechanical watch will not last forever it will need servicing. If your not buying new then be prepared for this. On an old chronograph it can be many many hundreds of pounds (assuming the watch is working in the first place) 

if you speak to someone who is new to watches and say your wearing a quartz watch they will lift up their nose in snobbery. if you speak to someone who really likes watches they will ask you what you like about it and take an interest. The former usually wears a rolex. And with that there is a lot of brand snobbery just like with anything else.

Nowadays they are jewelry and you should treat them as such. Buy one that speaks to you. one you like the look of. there are loads out there and they take design ques from many different places. Lastly buy one that you are going to wear. my first nice watch was a quartz omega i got when goldeneye came out. I dare not wear it because i didnt want to get it damaged. (interestingly i got the quarts for similar reasons as cougar. I couldnt cope with a 1500 quid watch loosing time) 

Practically a quartz wins and then an automatic and lastly a mechanical watch. Its annoying when you take a mechanical watch off and have to reset the time because you forgot to wind it. as a daily wear you wont have this issue with an automatic. my advice is buy one really nice watch. just the one. wear it everyday for everything.

This. Watches to me are jewellery or tools. In the working day I wear a "nice" automatic watch as I think it looks good and it tells the time well enough to not worry about. If I'm not around people I wear an old, battered solar G-Shock that keeps better time but looks crap with what I have to wear for work. I've also got a Garmin Fenix running watch that is a tool.

Or is it a case of this being a heart purchase and not a head one so just get the auto that started this query?

I'd personally get the one you like the look of/can afford/does what it needs you it to do, then worry about whats inside it afterwards.But push comes to shove I'd say auto, especially as thats what you seem to have started the itch with, though the journey and discovery is sometimes as interesting as the final purchase...

 

Unless you're looking at something like a Hamilton Khaki that comes in both varieties (then look at the Militado VH31 sweeping quartz version for a 1/10 of the price!).

 

If you're happy about the relative accuracy of both mech and autos and treat it like people have said as a bit of functional adornment with a good story about how you decided what to get then you can't really go wrong. If you are worried about accuracy fill your boots with a Grand Seiko Spring Drive in both mechanical and auto version to choose from if you want +/-20 secs a year....

1/10th!?

I've just bought a Berlenta from AliExpress which was half the price of the Miltado!  I got it to see if I liked the case shape, which I do so maybe an auto Hamilton is in the cards for the future.

That said, one of the main reasons I went for the Berlenta was the 40mm case rather than the more fashionable 36mm youth sizing on most watches of this type and I've not really looked to see who else does something in a similar size.
