Spring drive would spoil you.

I’ve got the new 3235 movement in my DateJust and it’s running around -0.3 seconds a day!

The accuracy of a watch also depends on the way it is worn and the activity of the user

Use a time graph .

I have a Traska, Summiteer with a regulated Miyota 9039 movement that gets +1 sec per day... you damn well should expect that from a Rolex!

Depends on how hard and long you wear them.

My AirKing, purchased August 2020, runs consistently 3-3.5 spd fast from new. My DJ 41, purchased 2 weeks ago, has been consistent at 3.5 slow. I wear both daily (work from home, and I rotate on my wrist).  My Omega SMP 300, purchased April 2020, ran 4-5 spd fast when new, but now has settled in to -1/+1 spd. It too is worn daily. Omega will run faster if I sit it face up overnight, slower if I sit it crown up. Both of the Rolex watches don't seem to care how I sit them on the bureau.

My Revue Thommen diver with Sellita movement is 2 seconds per day fast and it cost peanuts compared to any new Rolex. For that money they better make sure it's within 2 seconds a day! So why Rolex any better I ask myself all the time when a watch's job is to tell time?

Mine is a cheap Automatic from China, Forsining for only 35 U$ (bought last year).
It similar to Patek Phillipe Chronograph Geneve with date, day, month and 24 hour display.
I had manually tuned it with handphone stopwatch for 3 days and now, wolaaa .....:
The accuracy is pretty good, +15 sec/day in Horizontal and -10 in Vertical position.
I wind it up 10 to 11 turns every 6AM and 6PM a day.
Combine that position and wearing it for work, it can  achieve_, +/- 5 sec a day,. After a month of using, my watch still exactly the same hour and minute with world clock reference.

Austin what do you think about variability between the 5 positions?  Does the -4 to +6 guideline refer to 'on the wrist' or the average across 5 positions?  I find that there is considerable variability on the timegrapher between positions.  I also find that the variability between positions is much less for my two watches with the chronergy escapements (3235 and 3285) vs my older 3135 and 3187 movements.

well sadly the 214270 that I got in December was running between -6 and -9 a day. I will give the AD credit for taking the time to absolutely get it running perfectly in all positions. ( and yeah, running slow is just something I really hate as well. )

I think my 2007 Submariner finally needs a service. It’s losing loads of amplitude after 24 hours.

Rolex is designed and certified to run +2 or -2 seconds per day; however, you can tighten the accuracy further if the regulation is done correctly.

casio mrw200h ;)

While mechanical watchmakers are bending over backwards to sell you obsolete technology, Casio have added barometric, altimeter, and temperature sensors to improve their useability on top of their already impressive water resistance, and all for just a 1,000 dollars.

Honestly in terms of accuracy each watch differs and I believe we can never be expecting it to the point where everyone's happy;  Will people be seriously upset because it's not running the plus and minus within a tight range? I think it's just not realistic.   I've gotten a vintage Grand Seiko (6156-8000 Special) and this thing supposed to be promising plus and minus within 3 secs a day even at its prime; over time I believe even with high/frequent maintenance with watchmakers it will derail from that promised accuracy as it ages, are we going to lose our minds and love for the watch just because it's not "accurate enough?"  even when it's brand new? I personally don't believe so.  If so, maybe get a Grand Seiko quartz :-) Maybe could satisfy both luxury watch and accuracy desire.  
Thanks Austin for your videos, and I do look forward to my custom video request regarding the Air King Explorer.

For a watch at this price one can (understandably) expect great accuracy. (I expect some degree of accuracy in my automatic watches: under 8 seconds is just fine for me.) As tired and obvious as this suggestion sounds, it may behoove accuracy fetishists to settle for watches with quartz movements. One can acquire beautiful-looking, quality watches with impeccable accuracy. And it's easy to get the battery replaced every few years.

I have a date just that decades old date and is -3 second per per day. Before I inherited it wore my g shock mud master that syncs to atomic clock each day. I love the Rolex because grandpa wore it. My OCD wants it to be more accurate.

Grand Seiko is 15 sec / month ......
