Reply To: RR Pocket Watch Regulation

From an article attributed to Ed Hahn:
The constant in all of this was that railroad watches needed to maintain a standard of timekeeping of less than 30 seconds of error over a week “.

And keep in mind that it was ( is ) not acceptable for an accurate watch to lose or gain a large amount every day,..IE 10+ one day, and 30- the next, even if it averages out to meet the weekly rate.
Much better to have it gain/lose 4-5 seconds per day, steady. Better example of constant Isochronism.

So how’s it doing ???

Best regards,
