What makes you think automatic reps are unreliable? I've owned over 40 reps with all kinds of automatic movements (Swiss, Asian) over the years, and I've yet to have one die on me.
About that TAG Link... it's a nice rep but it's a fantasy watch. That particular looker comes only as automatic (gen).
But then again who really knows all the TAG models, quartz or auto. If you like that one, go for it! But then again if you want to check the alternatives before your purchase, you'd better read THIS.
