Obsessive with accuracy.

I'm not not obsessive at all. What you should do is get a "Radio-Controlled" watch that will always be spot on if you get the signal regularly and within 5 secs even if you only get the signal a couple times a month. I get a regular signal and I'm on the east coast.

I've noticed the jumping minute hand on certain, but not all ,Timexes and it drives me nuts too. But not to the point of not wearing. Also-there are ways to hack the Miyota non hacking movements aside from "back hacking". I do it all the time.

I’m not obsessive over accuracy, tho I have one watch that doesn’t have hacking and I do find that jarring whenever I go to set it. That said, I’m not doing anything mission critical that requires to the second accuracy, and even if I were, seems like it’d be a good day to strap on the G-Shock.

I'm obsessive enough about it that I plunked the money down on a spring drive to satisfy my desire for a mechanical watch with a high degree of accuracy. My Seiko LX only gains about 2 seconds a month, which actually makes it better than any of the quartz watches in my collection that don't have Bluetooth sync or atomic time correction.

It's absolutely more accurate than I need it to be, but it's a nice thing to have. I can only really tolerate about 10 seconds of deviation at most and with this watch, I could easily leave it alone for months before having to adjust it.

At some point I fully intend to get a Grand Seiko with a 9F high accuracy quartz movement. Those are rated to be accurate to within +/- 10 seconds a year, which will satisfy my desire for precision time keeping when it comes to non-radio controlled quartz watches.

I am trying to worry about it less, I might even sell my timegrapher so I quit testing watches. 

I’ve considered radio controlled just have not found one that speaks to me. It almost feels like the watch is cheating. 

I’m notifying the authorities. 

Ha, none of my five mechanical watches hack, so I'm liberated there. Quartz drifts to some extent and this does annoy me when it is noticed. 

If you have two or more digital watches with an hourly chime, turn them both on and synchronize. First of all, you'll notice that sub-second precision is impossible. They'll never chime at the same instant. Then, throughout a couple weeks or more, you can hear them drift apart till there are a couple seconds lag between the chimes. 

Ideally, hell yes I want set it and forget it perfect accuracy. I agree that about five seconds is tolerable, but much more than that (on a quartz) and it's getting reset. Laying a bunch of running watches together where you can see the hands in alignment to the second is a fleeting joy. Seeing asynchronization is dissatisfaction.

I usually wear a different watch everyday so I set it 1 minute fast in the morning if it’s an automatic/mechanical. If it’s quartz I don’t think twice. 

Problem solved 👍

It's fun knowing you have a really accurate mechanical watch but I'm not too bothered if it's fast or slow. 

Not at all.  The difference between 5 seconds off and 50 a day really has zero impact.  And I'm not into the technological challenges related to the tiny improvements in timekeeping.  I value other things so it just doesn't rank...

Does this answer your question?

I'm a stickler for accuracy as well. I have absolutely no need to have up to the second accuracy, but as far as I'm concerned the primary job of a watch (at least originally) was to show the time, and I feel that being able to do so accurately is a sign of a well made watch. I have different expectations for quartz watches than I do for mechanicals.

Most of my mechanical watches are COSC or METAS certified, and run well within 2-3 seconds per day. My best mechanical is my GMT Master II, which consistently runs <+1SPD.  I'm generally OK with anything better than 6 SPD, but the more accurate, the happier I am with the watch.

I also like having the minute hand line up perfectly so that it hits the appropriate marker when the seconds hand reaches the 12. Most of my watches don't have any "jitter", so that when I hack them and set the minute hand, there is no significant movement when I push the crown in. I do have some watches that always seem to take a few seconds before the minutes hand starts moving. My Norqain Adventure Sport chrono keeps time within +2SPD, but when setting it, I need to set the minute hand about a quarter of a minute fast in order to have the hands lining up properly.

My most accurate quartz watch is my Omega Speedmaster Skywalker X-33. When I purchased that one, I set the phase elapsed timer, so that I could see how much time it was gaining/losing over time. The PE1 timer currently shows that the watch has been running for 141 days, during which time it has gained only 1 second, which extrapolates to a gain of less than 3 seconds per year, which I find extremely impressive. 

Get an Seiko Astron   - And I need my watches to be accurate - I have some G-shock Wave ceptors that are always perfect

I just got a Grand Seiko SBGX261 with a 9F movement. I love the accuracy of the 9F quartz movement and the famous Grand Seiko finishing. Between the versatile style and more importantly, the supreme accuracy, I find myself wearing this watch a lot more than the rest of my collection. I love the accuracy of these nice HAQ watches.

I measure the accuracy of my watches almost daily using an app called Twixt. I always compare my mechanical watches to atomic time but only reset them to atomic time maybe once or twice a month. I like to see how different power levels and positions affect accuracy. I tend to notice rather quickly if a watch isn’t running within COSC parameters. Sadly, I’ve had to send in three watches (Rolex Yacht-Master, Tudor BB58, and Tudor Heritage BB 41) this year for warranty service because they were constantly running way out of COSC spec. All of them were losing close to -10 sec per day. 
 

The following are screen shots of the app Twixt where I measure the accuracy of the watches in my “daily” rotation. 
 

So you want accuracy? Buy yourself a Citizen 0100. +/- 1 second per year. 

Heard the newer one is even more crazy. +/- 0.5 second or something.

Just like you i am too, very obsessed with the watch that i will wear for that day, it needs to be "hacked" before i even place it on my wrist. Be it mechanical or quartz. And 24 hours later i will check if it has kept / or kept as close to ZERO ZERO ( that is +/- 0 seconds / 24hour period) and record that down, to keep track of the performance of that particular timepiece. I enjoy the action of doing this, and have been doing so since i got my 1st watch back when i was 5 years old or so?( a flik flak back then) , all the up to my very 1st mechanical ( a Breitling for Bentley ) and thereforth. Keep doing what you have been doing my friend.

I'm not really bothered by wristwatch accuracy as long as it's within +/- a few minutes because I really use them only to get a rough estimation of time to keep me on track.

It used to be really important when I was not surrounded by a multitude of time keeping devices and when there were no cell phones to ease coordinating meeting and update parties on delays because being late or missing meetings was a real issue back then. But now I can pull out my cell phone and get a time that is not only as exact as it needs to be but is also uniform among all other cell phone users.

I like to know if a watch is way off, so I can anticipate than during the day. Worst offender is a vintage and never serviced Timex that loses four minutes a day. That's a watch I wouldn't wear on a day with appointments I want to be on time for.

On the other end of the spectrum I have a COSC certified quartz that is one or two seconds off in the half year between summer and winter time.

When it's about seconds I really don't care much, even between multiple radio controlled clocks and checking world time server there is a bit of a difference, so  who actually knows what time it is? 😉

My Grand Seiko SBGA463 is super accurate. I am into accuracy because I spend money on a timekeeping device that purports to keep accurate time. I am a stickler for all of it: accuracy,  METAS,  Safely, COSC, ISO,  water resistance etc. Why? All these watches pitch us these attributes as important so give me the specs. We can tell accurate time off a smartphone. Watches are not a necessity. Since we buy them they should be real good at their designed function. If I purchased a sports car that had crap performance it would be a problem. If I purchased a firearm that didn't go Bang when I pulled the trigger every time it would be a problem. Watches are no different. 

Sounds like you need more radio or Bluetooth watches. There's even a good looking GPS watch (maybe more than one I didn't check) from Citizen that knows exactly what time zone you're in as well as the exact time.  

Me personally I don't mind too much. My watches are quartz and two of them have my daily alarms and they go off within a couple seconds of each other, and one of them is atomic. So I never think about it really 

Sound like you should get a 9F quartz from Grand Seiko? Or maybe the new Citizen quartz that's 1 second of a year max. + G-Shock with multiband 😊

My CWC G10 is incredibly accurate and I tend to set it to the second. However my Speedy doesn't hack and isn't accurate so I just let it go.

I am like you.  I am pretty obsessive about accuracy, and the minute hand must be centered.  I am okay having some watches that are not that accurate ( I mean I do own quite a few Seikos 😂), but the main watches I wear are accurate.  My most worn watch is a Sinn 556A that for the most part gains or loses 1 or 2 seconds a day, and my weekend watch is usually a quartz Grand Seiko that has only gained roughly 2 seconds over the last 10 months.  I also wear a Seiko Tuna with the 7C46 quite often, and it gains only about 5 seconds a month.  Maybe I am crazy, but I am impressed with a watch, quartz or mechanical, that with no outside assistance is as accurate as possible.  It is a true testament to the people that put the time and effort into creating a tool that helps us keep track of the one thing all of us are racing against.

same here. When I read that my € 1300 Formex Essence has only gained 2 seconds over 24 hours, I have a big smile on my face for the next ten minutes

My best performing watch is probably the BlackBay 58, typically in the -2/+2 per day range. If it's good enough for Rolex, it's good enough for me

the worst performer is certainly my 1998 Speedmaster, probably 15-20 sec fast per day. It's okay though because the running seconds counter is pretty small and I rarely wear it more than one day. And 1861 caliber Speedmasters always get a pass anyway, because they're so cool

I've been thinking about this thread since yesterday.

I'm retired. I rarely have important appointments. When I do I set a calendar reminder on my phone.

Occasional I put on a watch without realizing it's not running. I can go the entire day with the watch set to the wrong time.

I love accurate watches because of the be amazing technology. I wear them because they are asthesicaly pleasing.

I’m not that obsessive about accuracy but i do adjust the time on my automatic watches once a month or so. 2 months ish for my digital watches.

That said, my Seiko SKX 007 and king turtle are pretty accurate, for now. Lol
