A good mechanical watch is a testament to a man craving a little toy he can carry around with him to admire, for centuries.
For a century or two they were so imprecise they didn’t have an minute hand.
Then in 1857 Waltham made the first industrialized watch, which sold for a hundred dollars.
In 1883 Waltham improved their movement, and made 5.4 million 1883 model watches over the next 37 years.
This post describes the cleaning and adjusting of a Waltham 1883 (Grade 825) 18s pocket watch to 3 positions.

I own a 15 jewel Crescent Street grade 1883 Waltham made in 1892 in a Hunter case, that’s been keeping railroad time for over 130 years.
But it’s hardly worth anything, because it’s a railroad grade movement in a Hunter cased watch.
I own another 1903 Waltham 1892 model 23 jewel Vanguard in a Hunter case that has a lot more cool factor, but is not worth much more nor does it keep better time. Once you get about two seconds a day or less, it’s hard to improve accuracy.
Those old high grade watches would cost a fortune today, if duplicated.
We are all quite happy with the Swiss 2824 or any of the legion of Japanese or even Chinese clones or homage movements that average about 15 seconds a day.
One advantage of the Seiko, Citizen, and Orient automatic movements is they beat six times a second instead of eight.
More beats per second has more accuracy potential, no argument.
But I own two Seiko automatics that have kept good time for over twenty five years without service. The tiny improvement in accuracy potential of a high bear watch requires more frequent cleaning, oiling and adjusting which today is usually more than a replacement new watch.
