    Hello Gary – please could you say what make and model were the three watches you used for your experiment? I tried but failed to find the photo you posted.
    On this subject – before reading about Gary’s experiment I was thinking recently of doing something similar myself with a few Casio F-91W watches. I then remembered I had an old one buried somewhere and finding it it turned out to be a predecessor – a Casio F-84W which I bought in England in 1988. Unlike the F-91W which is given a place of honour on the Internet, there is hardly a mention of the F-84W and most of it is in Japanese. Anyone familiar with Casio quartz watch history? Was it a model not widely available in the west?
    In any case I loaded it, and also a fairly new and much more expensive Timex Expedition i-Control watch which I also have, with new CR2016  batteries last night and set them to precise UTC. The Timex is already a second out this morning whilst the little old Casio is still smack on. I will follow the two during the next weeks and months and report.
