Measuring watch latency

Post02 Apr 2015, 14:36

Hi all. :)

I was trying to measure a P2 over 24 hours. I used my phone at first, then a modern Casio watch's stop watch, then another modern Casio watch's stop watch, and a 15 year old Seiko watch's stop watch. I noticed that if I started them all at the same time, after 24 hours, everyone had drifted slightly in a different way. :scratch:

Is there any other method I can try (without buying any new kit)? Maybe an online clock, or something similar?

Thanks. :-D

Since I don't currently own a radio controlled clock or watch, I set all of my timepieces to the online atomic clock in the USA.

The following is a World Time Server link to UK time:

Thank you both. :-D

I have been using a modern basic Casio for timings. I will give those web sites a go. Cheers!! :mega:

This may solve the setting issue, but not the accuracy. You need a quartz monitor to have any chance of adjusting your watch to as near-zero frequency error as possible.
