Drives me crazy

Agree with others. If you want an accurate mechanical watch, then buy and wear just one watch. You can then regulate it to your wearing patterns, and you should be able to keep any modern mechanical watch to well within COSC specs. I built a watch with a basic ETA movement (the movement cost me $200), and that watch was accurate to within a couple seconds a week. I gave it to a friend, who doesn't wear his watch at night, and has a different lifestyle to me, and the accuracy is not nearly as good.

Just because I wanted to know.


My 16713 runs <2 seconds fast in 24 hours, worn 24/7.

Proper beat rate is; 28,800/hour, 480/minute, 8/second, 691,200/day, 252,288,000/year.

Let's say mine (for the sake of argument) at just a bit less than 2 seconds gain per day is.... Call it 14 beats too many.

So out of possibly being exact at 691,200 beats in a full day, mine does 691,214.....or out of a perfect 252,288,000 beats a year, mine is adding just 5,110 beats to that. that's ...... 638.75 seconds added in a year of 31,536,000 seconds. 1/49371.42857142857 ratio of accuracy.

On a percentile that's an error of 0.0020254 %...

So it's accurate to 99.9979746 % day after day, after day.

The clock in my laptop is more errant.

Stunning accuracy for springs, staffs, gears and levers. Hundreds of parts.

In the long run this is leagues more accurate than any battery watch. Due to the fact when the battery expires, the auto-winder just keeps right on ticking, without missing a beat or at least, a few anyway.

But who's counting?

I don't get some of these posts about "letting it go". What is wrong with buying a Rolex, or any expensive watch, and then taking a keen interest in its accuracy, and how it runs? I get a lot of pleasure from noting how my Rolexes keep time. For me, its a big part of owning them.
