I have decided that I need a new watch even though my trusty Timex Expedition is functioning flawlessly.  I started looking for a diver in the under $500 range and found several Seikos in the Prospex line that I thought would be suitable, particularly the "Save the Ocean" turtle SPRD21.  Obviously, this is a genuine dive watch that has a fashion look but also, given my eyesight, is fairly easy to read (not the day/date which is worthless to me).  But then I read that Seiko's standard for accuracy is up to 45 seconds per day and wonder if automatic watches are a hassle.  So, do you find the adjusting of automatics a hassle or no big deal?  It would be easy if the best looking watches were available in their solar movement but that doesn't appear to be the case.

To answer the question, yes I find them to be a minor hassle, but the fussiness is part of the experience. YMMV. If you really need second-type accuracy over days or weeks, a quartz/solar-quartz watch is the way to go. Autos fall in a spectrum of good-enough to “almost quartz” as far as accuracy. Most of mine are +/- 30 seconds per day, which is sufficient for my needs.

Most of the Seiko autos will run much better than the maximum deviations... the majority of mine run +10 sec/day or better.

I find I either rotate my watch out for another before it becomes a hassle, or if I'm on an extended kick with a single watch... I correct the time about once a week.

Even quartz will show beat error over time. My 300M quartz Tuna runs about 3 seconds fast / month... so over time it gets pretty far off of the atomic clock. I have to correct it occasionally to settle the OCD down.
My solar tuna-lite also shows beat error... it's running about +8 seconds / month.
Only watch I have that is 'dead on' all the time is my apple watch... and it's a soulless hunk of tech.  It brings no joy, but it does offer utility for heart rate / gps / etc.

The allure of the mechanical movement more than makes up for the beat error issue to me.

That's 15minutes a month! I would not accept that. The newest one I bought was similar. I took it and paid $20 to have it regulated. It's now -3 seconds a day. That <2 minutes off a month or about 5 minutes off every other month when I change the date and correct the time.

OP - It’s a bit of a labor of love. A few seconds +/- a day is no big deal to me. A good auto might need a once a month time hack.  I gain far more enjoyment from wearing an auto. Kind of like loving a car with a standard transmission or carrying a nice 1911.

There's no difference for me between +/- 5 sec or 30 sec since I rarely wear the same watch more than two days in a row. After that they're in the case and their long-term accuracy doesn't matter. For real short term accuracy 5 sec or 30 sec/day doesn't matter since they're both wrong anyway. For SHTF I'll be wearing a solar Casio.

For me, I'm not impressed with the concept of automatics that may be several minutes off each week to 10 days.  I had to replace the movements in a couple of my Seiko SKXs to get to where they kept excellent time.  Personally, I'd rather have a quartz diver and spend $10 for a tool to remove the caseback so I can replace the battery myself.

If you're looking for a quartz diver, look into the Diver One quartz line from Scurfa Watches.  I have one, I absolutely love it.  I think mine was $280?  They sell a metal bracelet for it too.

Sounds like people have different experiences.  10 seconds per day isn't too bad but 30 (or more) sounds like it would be a hassle.  Of course, I'm not sure how I would use the watch.  If I was using it only on weekends, winding and setting it before using it wouldn't be too much effort regardless of how much time it lost.  As a daily watch, resetting every week could get old.  Maybe I need a nice quartz and a nice automatic.

I was an automatic aficionado for a long time.  Now all of my autos are gathering dust. I now much prefer the accuracy of a battery-free Citizen Promaster Eco-Drive. Rugged, inexpensive, maintenance-free...and looks awesome doing it.

Having an automatic is sort of like having a pet.  You have to be aware of how it is doing and feed it  if it is hungry (i.e. running down) or take it to the vet (watchmaker) if it is feeling ill.

I have an automatic, a Sinn U2 and a solar G-shock.

The Sinn puts a smile on my face every day.  I hardly ever wear the G-shock -- it doesn't have the personality or soul that the Sinn does.

If I only had/wore a single watch, it might be a bigger deal, but since I rotate through a couple, and set them more frequently, its a non-issue.

It's not really a hassle, they just require a little attention, which is part of the experience.

I'm unlikely to ever wear a quartz again. I love my autos.

So I bought the Seiko and it seems to be within a few seconds per day.  The problem is that I can't set the day of the week!  I'll do a separate thread on that problem.

OP I own more than several autos.  It's a much different relationship than with a quartz watch.  

In short, you will be welcomed to a more relative, and relaxed, relationship with time.  It's a little motor on your wrist ticking away at its own beat to keep accurate time.

Whether it's a Seiko (my SKX007 keeps great time if worn regularly), or a COSC certified Omega, Breitling, Rolex, etc., they all have excellent time keeping qualities.  While my better autos will never equal the day to day accuracy of a well functioning quartz watch, many of them come really damn close.  Do the math on +/- 1, or 2 seconds per day, you're still well over 99% accuracy.

In truth, I rarely set my autos to the second, only to the minute. As I said, it's a more relaxed relationship.  It's fun to know that your watch is accurate to the second, but is it necessary? Only in a couple of jobs I can think of.

That is what I do, it bugged me at first when I changed from quartz/digital but in the greater scheme of things it is a minor hassle.

I don't swap out watches unless it is a particularly special occasion though.  I pretty much wear my Seiko 24-7 365.

Link Posted: 5/7/2021 7:50:15 AM EDT

Not at all. My only Seiko is a prospex samurai Pepsi and it gains +4 seconds a day when worn which is really good. I just reset it once a week or so because I’m anal. If I take it off overnight (rarely ever take my watch off to sleep) it will gain like 8 seconds overnight so it definitely prefers some movement. Still doesn’t bother me though.

My Breitling Superocean 46 on the other hand gains exactly 11 seconds a month and doesn’t care if it comes off the wrist overnight, how much movement I’m doing, or anything. That watch is simply amazing, but you can buy 10x Seiko Prospex Samurais or Turtles for what it cost. I wouldn’t trade it for 50 Seiko’s though, well unless they were grand Seiko’s or Lux’s in which case I’d sell them all and buy more Breitlings.

Yup, they were $88 for a day. I even posted it here in the deals thread.  Still kick myself for not snagging a few at that price.

That's it! It was that post of yours that turned me on to the Promaster. Even at $106, it was a hell of deal and money well spent. It's been my EDW ever since.

I ended up returning the watch (see my other thread) but I bought a replacement.  The replacement watch, so far, is about 30 seconds per day off.  I haven't worn it since I want to be able to return it if it doesn't work out.  30 seconds per day means I would need to reset it weekly although that doesn't seem too bad.  I'll monitor it for a few days before deciding but it's a good looking watch and I think I can live with resetting it weekly.  As I mentioned previously, perhaps I will also get a quartz watch (Citizen Promaster Diver).

Unless you go the chronometer route, it’s just hit or miss. My Seiko SPB143 runs -2.5 a day, which is incredible for an unregulated 6R35 movement. My Speedy is +5 a day, also lucked out. A couple of my Seikos are anywhere from -10 to +12. Seamaster and C Ward chronometer are both within a second per day.

I have that exact watch, and yes, mine gains time and probably needs to be adjusted. I just end up arriving early by a few minutes as the week goes on and reset it on Friday.

It looks good, it’s mechanical, and it’s ready for relaxing on the beach or the end of the world.

I rarely wear my watch (Orient Mako USA) every day. Usually it is Saturday that it doesn't get worn so I set it on Sunday. So in reality it doesn't matter to me that much. But this thread made me curious. Over the course of the last week it gained a total of 5 seconds. I don't wear it when I'm sleeping so position overnight definitely effects its accuracy.

For me, wristwatches are jewelry, so as long as they are somewhat kinda sorta accurate over a month or two, I really don't care.

I rotate watches so I just let them wind down until I come back to them a few months later.

If you DO need an accurate wristwatch then something with an Eco_Drive is probably your best bet.  My Citizen Paradigm is extremely accurate.  You might have to maintain one every ten years or so...maybe.

Have a Seiko King Turtle with the 4R36 movement and it's very accurate at ~ +4 seconds a day. Have an Explorer II (216570) that's as accurate but at 25X the cost of the Seiko.
