I can say that I am extremely impressed and pleased with my purchase. This I my first automatic and my first Ball. The attention to detail and quality of construction is outstanding, especially considering the price. I have had a chance to compare it side by side to several friend's watches (Panerai, Rolex, Breitling) and I am not disappointed. I love the tritium lume! This is what drew me to Ball and this watch. 80 tubes and 3 colors. I already had 2 Luminox and Ball was the logical "upgrade."
My watch is keeping excellent time. I have found that if I lie it dial up at night, I lose 2 seconds per day. Even this is well under COSC -4/+6 standards. If I keep it on my winder at night, it gains a second or so per day. In over 3 weeks of run time, it is now only 10 seconds slow total! If I could change anything, it would only be to recess the pip in the bezel. It has a sharp edge that can catch the edge of a pocket or the underside of a shirt sleeve.
Lastly, thanks to all that post here regularly. I used this site for research prior to the purchase and it was extremely useful. Special thanks to Samanator!
