So do I, and I'm based in the UK! It's better than the UK option (as usual :roll: ).

That's the site I use too. I reset my Superocean II once a week every Friday. Today it was about 25 seconds fast.

COSC is -4 / +6 seconds per day.

It isn't just accurate - it is THE time. The atomic clock based at the U.S. Naval Observatory.
How do we know? By definition – the International System of Units(SI) has defined the second as the duration of 9192631770 cycles of radiation corresponding to the transition between two energy levels of the caesium-133 atom. Got that?! Me neither.

And 15 seconds fast in 3 days is 5 seconds per day. That I get. COSC specs are -4 to +6 seconds/day. I get that to.

Congrats - you are wearing a fully functioning chronometer. :)

In reality, any decent quartz watch is good enough to time a mechanical.

But I use the Strata 1 time server that we have on the network at work.
