I own two Lange's and both of them had some issues and in both instances Lange acted promptly and fixed things for me. You can read about them here:

What happened with you is extremely unfortunate but i wouldn't be too quick to brush ALS off or even assume this is their standard. The ALS Thin 37mm is every bit Lange and there is absolutely nothing entry level about the watch despite the price.Its a superb timepiece that perfects simplicity- not to mention its superlative hand-finished movement, puts the holy trinity to shame.Out of all my watches its the one i find my self admiring and wearing the most- i have handled FPJ, AP and PP among others that had so many flaws and in one personal experience with PP, the salon refused to own up to the faulty watch but took it back for 8 months to repair- ruins the joy of owning a brand new watch.I know of a few instances with AP and FPJ that will shock you- point is, these companies are not flawless and mistakes happen, its how they react to them that matters.
As you have experienced, Lange's customer service is beyond reproach and the fact that the brand president herself responded to you shows you their commitment to make things right- trust me, they will make it right.
Do yourself a favour and give it one more try, this watch is perfection.
