Lange's movement finishing is better than just about anyone else. Every piece is double-assembled. Yes, Lange did have a little fiasco with early produced 1815 watches that didn't have their proper movement finishing on the hidden internals; but despite that, Lange is one of the best timepieces on the market, better than even the established Swiss brands. It's a great value, Patek Philippe and Vacheron Constantin don't start double-assembly until about the perpetual calendar or around 100,000 Swiss Franc price point where all Lange models have it starting at around 18,000 Euro. It's just about finding the model that speaks to you! And you only need one masterpiece!
