This is not the most hype Lange or the most sought after Lange. BUT, in my eyes, one of the most beautiful, and among my favourite watches.
Wonder how this would look with a black dial.






About the A. Lange and Söhne Ref. 1815AnnualCalendar

The A. Lange & Söhne 1815 Annual Calendar, reference 238.026 (white gold) and 238.032 (pink gold), was introduced in 2017 as the first annual calendar in the 1815 collection. It offers a more traditional aesthetic compared to the Lange 1 or Saxonia lines, aligning with the classic design principles of Ferdinand Adolph Lange's original pocket watches. This model provides a practical calendar complication that requires adjustment only once a year, at the end of February, making it a functional yet understated daily wear option for collectors who appreciate classical watchmaking. It bridges the gap between simpler time-only models and more complex perpetual calendars within the brand's offerings.

The watch features a 40mm case, available in either 18k white gold or 18k pink gold, with a thickness of 10.1mm. The manual-wind caliber L051.3 powers the timepiece, offering a substantial power reserve of 72 hours. A sapphire crystal protects the silver dial, and a sapphire case back allows for observation of the meticulously finished movement. The water resistance is rated at 30 meters, suitable for everyday wear but not for water sports.

This reference appeals to collectors seeking a technically sophisticated yet visually balanced timepiece from A. Lange & Söhne. Its annual calendar and moon phase complications are thoughtfully arranged on the dial, maintaining legibility without appearing cluttered. The 1815 Annual Calendar represents a significant addition to the 1815 family, offering a compelling option for those who value traditional design, mechanical integrity, and a useful calendar function without the added complexity and cost of a perpetual calendar. It is presented on a hand-stitched leather strap.

I understand the appeal, but it doesn't speak to me personally. Too much going on and three cut numerals. Simpler is better for me. Best, Emmanuel

As far as a black dial, could be more dramatic, but I really like the dial on yours. Must bring a smile to your face each time you put it on. Here's a question - what's the ratio of looking at it for the time, and looking at it as the work of art it is?

Do you prefer the Patek and Laurent Ferrier Annual Calendars?

It is not mine. I tried it on during Dubai Watch Week. But I really like it. I would be happy to own it. It would complement my Lange 1 very well. Its been in Lange's catalogue since 2017, yet does not feel dated in any way.
