The seconds at 6 Daytonas are bad news. There are also the Seconds at 9 Daytonas which are fine, as well as the vintage Daytonas with the Lemania/Seagull manual wind which are solid. Accuracy on the vintage ones is the issue. Personally, I don't care too much about the vintage accuracy given Rolex has made so many variations to dials, bezels, etc it's really hard to keep track of everything.
BTW...thanks for sharing. The Link bands are still referred to as one of the most comfortable around.
