The TZ-UK British Summer Time timekeeping challenge

[JGJG]

I'm going to pull out of this - travel means resetting the time, and I want to keep wearing the GS, so I'm going to self-disqualify!

It's a great thread idea and it's shown me just how accurate the 9R65 Spring Drive movement can be at +0.25 seconds per day, far surpassing GS's own accuracy claims.

Thanks again for organising this JGJG.

You're very welcome & I'm glad you enjoyed finding out a bit more about the behaviour and accuracy of your watch, which was the whole idea. Enjoy your travels :)
