A. Lange & Söhne Tourbillon PLM Vintage

Key Points from the Discussion

• The A. Lange & Söhne Tourbillon Pour le Mérite was considered incredibly expensive and a true 'stunner' upon its 1990s release, making it a aspirational piece for many collectors at the time.
• The provenance of this specific Tourbillon Pour le Mérite is particularly unique, as its sole previous owner was a member of the 'Lange' family, adding significant historical value to the timepiece.
• A key detail often admired in Lange movements, even on the dial side, is the meticulous alignment of the screws securing components like the tourbillon bridge.
• A common technical question regarding vintage or early modern high-horology pieces like this Tourbillon Pour le Mérite is whether the front crystal features anti-reflective (AR) coating.
