Aren't the IWC specs -0 to +7?

Thanks,

Hi Donald,

That could well be the case, I didn't look it up before posting. Somehow I had these figures in my mind.

Kind regards,

Clemens

The COSC standard for chronometer specification since 1973 is -4/+6 seconds per day where the testing period lasts 15 days.
Kind regards,
