I am wearing this one now since i got it earlier this year. This piece holds time like no other watch I ever owned before. Within the first ten days, it is right on. I wear it 24/7, so the last time I had to set it was when I adjusted the date end of February. Since then I daily check with NIST time and today it is about 8 seconds fast since 1. of March when I set it. That's not bad, 8 seconds fast in 45 days.Today Georg JensenView attachment 1056141
