First introduced in 2001, the A. Lange & Söhne Langematik Perpetual is the firm’s first self-winding perpetual calendar wristwatch produced featuring the manufacturer’s off-centred 21K gold SAX-O-MAT rotor. Powered by the in-house cal. L922.1 with zero-reset function composed of its signature German silver, it indicated moon phases and leap year featuring its iconic oversized date display at 12 o’clock. An impressive movement, the perpetual calendar is accurate up to the year 2100 if the watch is consistently running.

The present example Langematik Perpetual belongs to one of the rarest variants featuring a 38.5mm case in the firm’s patented 18K honey gold featured only in special limited edition timepieces by the firm. Released in 2019, the honey gold edition was limited to only 100 pieces. Being a more robust material than regular 18K gold, the honey gold was developed not just for its aesthetical attributes but a material more scratch-resistant than its regular counterparts. Offered in pristine condition, the present example numbered 45 is complete with its full set of accessories and is a wonderful and rare example, a perfect addition to any Lange collection and a practical and elegant timepiece even for daily wear.
