Perpetually beautiful. The A. Lange & Söhne Lange 1 Perpetual Calendar, ref # 345.056, caliber L021.3. So much information packed into a beautiful, logical and legible display. An LE of 150 pieces.
Great travel watch. While not as popular as a GMT, I have a strong preference for a dual time, much simpler for me to read while traveling. Here on a Delugs strap.
