Has anyone had their Port Auto regulated?

My Port Auto is running +10secs a day which I find to be unacceptable. Has anyone sent their watches in to get regulated? If so, what were the results? Did you send the watch back to IWC or can any competent watch repairman do this?

It is up to you

But keep in mind that 10 seconds out of 86400 means an accuracy of almost 99.99%. Quite a feat for a mechanical device.

for me 10 sec is no problem...

Mine started out at +10 sec/day too..

But has settled at somewhere between +6 and +8 sec/day after a few months.

For me, this is acceptable so I don't send it in.

Kind regards,

what are you measuring it against?

My Junghans...

Radio controlled wall clock. It syncs every hour with the Atomic Clock from Frankfurt.

Kind regards,
