I though it might be fun to pose a broader question to the forum, one which any enthusiast can answer and which doesn't relate to any specific Lange watch.
Based upon your love of watches, what is Lange's single most attractive quality to you? You can choose only one thing about the company or its product that excites you or that you admire.
For me, I am most impressed by Lange's exquisite attention to the finest of details. This can be in the design of the movement or of the dial, or of the high level of finishing each watch receives regardless of complication or price point. I have great respect for a company which so carefully considers every decision and is so attentive to even the slightest detail.
