My Portuguese is two minutes fast every month...is this normal?

Anyone?

Hi Pierre,

I don't own a Portuguese but 4 seconds a day sounds normal to me.

Just for argument's sake consider that you can have a movement COSC certified doing between -4 to +6 seconds per 24 hours.

Cheers!

Hi Pierre,

Two minutes fast in 30 days is about 4 sec. fast in a day which is great for a mechanical watch. IWC tries to regulate their watches between 0-6 sec. if I'm not mistaken, and that is well within the COCS rating of -4 to +6 sec. (please anyone correct me if I'm wrong). So your watch is doing a fantastic job! Enjoy and wear her in good health!
