Kinda ironic to call a 20 second loss as 'accuracy' lol. Oughta call it what it really is 'inaccuracy'.

I'll disagree here. A day has 86400s. Assuming a 40s error/day, this works out to an error of 1s every 2160s. Less than a 1s error every half hour.

And this is for a mechanical automatic movement - powered by gears with no electronic components whatsoever.
The amount of engineering it takes to achieve this is insane
/end JZ voice
And I gather the NH35 is a robust movement in the sense that it can run for like a decade without any servicing?
Absolutely ridiculous for the movement price (y)

I agree that the stats are not bad, and we can adjust too. But I just think that it would be better named as to how inaccurate it is as we are dealing with an error or fault in 'perfect'. If you saw what an artery looks like after an angioplasty without a stent, you might be horrified, lol, because when they heal weeks after, they look much better. It's acceptable, but we wouldn't call it looking 'perfect' by any means. In fact, we call it a residual 'defect' or 'abnormality'. It's just a matter of how you look at vocabulary. If it ain't perfect, that it's inaccurate, but buyers need that warm fuzzy feeling, so they call it accuracy instead of inaccuracy, which it really is. [half empty vs half full to some I suppose].

Just like a "pre-owned" vs a "used" car.
 
With the watch sitting with the dial down for a day, it seem to not lose more than 3 seconds.
 
I'm always on time and have never been late. Even without wearing a watch. I just don't get how some folks are so anal about + or - seconds that are in an acceptable range.

Accuracy of Mechanical Wristwatches - What to Expect
In the world of mechanics, anything assembled of small parts which are capable of maintaining 99% accuracy would be considered a top-tiered piece of machinery. To put things in perspective, if a watch is only 99.9% accurate it would be off by 1 minute and 27 seconds per day, which is unacceptable in the luxury watch world.

Accuracy is dependent on a few variables, such as:

  1. Position: Due to gravity a watch will gain or loose more time if laid to rest in a single position. The balance wheel has been adjusted to compensate for losses and gains in different positions. An adjusted watch should perform overall within the specification when worn throughout the day. If you remove the watch at night you may want to find the optimum position that will compensate for drift during wear.

    Watches are typically adjusted to between 2 - 8 positions:
    1. Dial Up
    2. Crown Down
    3. Dial Down
    4. Crown Left
    5. Crown Up
    6. Crown Right
    7. Half-way position crown up
    8. Half-way position crown down
  2. A watch adjust to 2 positions has been adjusted to the first 2 positions, a watch that has been adjusted to 4 positions has generally been adjusted to the above 4 positions and so on.
  3. Temperature:
    Watch Temperature
    The environment may have an impact on how accurate the watch operates. Temperature changes expand and contract many of the parts, changing the dimension and shapes - especially the balance wheel and hairspring. In modern watches most materials and designs are able to compensate for the changes and maintain a consistent rate. This is generally not a problem unless the watch is constantly in extreme weather environments and is corrected by a very simple regulation.

    The standard acceptable accuracy of mechanical wristwatches is as follows:
    Modern Mechanical non-COSC Certified watch
    Worst Case Scenario+/-10 seconds per day99.988% accuracy
    Typical+/-5 seconds per day99.994% accuracy
    Excellent+/-3 seconds per day99.996% accuracy
    Modern Mechanical COSC Certified watch
    Worst Case Scenario+6/-4 seconds per day99.994% accuracy
    Typical+/-3 seconds per day99.996% accuracy
    Excellent+/-1 seconds per day99.998% accuracy
It is important to understand that a fresh watch off the shelf may need a break-in period of a month or so. This allows the watch to find its beat and distribute the lubricants evenly. If you find the watch not to be as accurate as you would expect after the break-in period, there are generally two courses of action to increase accuracy - both being minor in nature, but require competent watchmakers to perform:

  • Regulation: This is for a watch that runs consistently too fast or too slow - the keyword being "consistent". The solution would be to regulate the beat rate accordingly. This is a very simple and relatively quick procedure achieved by turning a screw. With the appropriate time-measuring machinery a qualified watchmaker can accomplish this in a matter of minutes. This procedure is probably one of the most common tasks for a watchmaker.
  • Adjustment: This is for a watch that is fast or slow or does not have a consistent rate, especially in different positions. The balance wheel needs to be adjusted to compensate for the different positions. Although this too is a simple procedure, it does require a little more time to correct as each position needs to be monitored and adjusted.
 
The average of dial up and dial down would put me under 10 seconds
 
Our time clock pays us right up to the minute rounding out the seconds so that doesn't matter. I will just stand there pissing off the dragon lady from human resources if I see her around. She rolls her eyes at me while waiting to punch in the exact second and I will do the same thing when clocking out. She has steam coming out of her ears seeing someone loitering on company time if she happens to be around. That's the great thing about keeping logs as a driver. She once had to pay me thousands in time differentials because of the shift I was working. She gave me a check and said I hope we are settled now. I told her actually it is off you still owe me several hundred more. She told me her assistant was off and she would check it, sure enough I received another check. The warehouse manager said why did you have to do this on my watch? I said it has nothing to do with you. If I was paid the correct hourly rate for the differential it would not have been an issue.
 
Our employees now have a thumb print scanner to clock in. It seems that others were punching people in and out to arrive late and leave early. but we docs stay out of the employee stuff for the past decade or more. I used to interview the nuclear medicine staff before hiring, but not any more. This is why they hire people that don't know squat...to fill vacancies and satisfy numbers. Latest fiasco at new equipment. First they tried to buy low end crap and ask me to sign that I agreed with the purchase. I refused. Nest they decided to ignore my suggestions about where to install, which has resulted in the staff being separated and unable to help each other, so they try to do everything on one machine...the older one that they know better. They claim that they are frustrated that this is happening and ask for my help. I told them that they should have listened to guy with over 30 yrs experience, so since they think that they know better, they need to figure out how to fix the problem that they created.

Should be here tomorrow. If I'm here to sign for it. :cautious: I always forget Aragon ships signature required and I'm never hear when it arrives.

If it is USPS you can sign up for informed delivery and enter an electronic signature then it will be left even if you are not there to sign.
 
I once was signed up for informed delivery then one day poof, wouldn't work anymore and won't let me sign up again. Says in ineligible. Whatever.
