TAG vs Rolex

[scottjb411]

I received a tag formula one for graduation in 1996. Over the next 10 years I beat the tar out of it(not intentionally). Since it was so reliable I purchased another newer model a couple of years ago. It being a quartz model I assumed the accuracy would be decent. I soon noticed that my rolex datejust (of course with self-winding automatic) kept as accurate, if not better time than the battery powered quartz tag. My understanding is tag boasts the movement should only lose or gain 1 to 2 seconds over a year. Tag is a good entry level Swiss piece, but rolex is my favorite bar none.
