What is the normal deviation when you wind up your new Tag Heuer Carrera LE Monaco grand prix with Calibre 16, I mean wind up by hand (not wearing it)?
Why I ask this? I also bought an Breitling Avenger Seawolf, this watch is still, after 1 week, even to the automic clock. No second deviation.
The Tag is every day 1 minute later, so after one week it's 7 minutes later then the automic clock, is this normal?
Sorry for my bad english, it's not my native language.

My Carrera has lost about 9 seconds in the last 2 weeks but that's better than the average I think. Sounds like your TAG is worse than average and your Breitling very abnormal for an automatic watch!!

The Breitling has an COSC and the Tag not maybe that's the difference? But do I have to go back to the jeweler I bought it from?

My Carrera D&D runs about a minute per week fast.

The Cal 16 is a ETA/ Valjoux 7750. Even in it's most basic version it shouldn't vary by more than +/-5 seconds a day. If your watch is new you may want to see if you can swap it out for another. Otherwise it may need a service or a regulation.

Valjoux Specs per wikipedia:


  • the Elaborated grade is adjusted in three positions with an average rate of +/-5 seconds/day with a maximum daily variation of +/-15 seconds/day;
  • the Top grade is adjusted in five positions with an average rate of +/-4 seconds/day with a maximum daily variation of +/-10 seconds/day.
The Chronometer grade must meet strict standards prescribed by the [COSC]: an average rate of -4/+6 with a maximum daily variation of +/-5 seconds/day.[SUP][11][/SUP]
