The 1815, released in 1995, was a "basic watch" designed with the average user in mind, not for enthusiasts. However, the 1815 is a very interesting example when considering the future of A. Lange & Söhne and German luxury watchmaking. At first glance, the 1815 seems unchanged from its debut. However, the truth is that it has changed dramatically over the past 20 years.

Günter Blümlein, who drove the revival of A. Lange & Söhne, seems to have had Patek Philippe in mind when he was reviving the brand. Since he passed away in 2000, I have no way of verifying whether this is true. However, some people involved say that he was trying to come up with a different approach than Patek Philippe.
This is exemplified by the four models first released in 1994: the Lange 1, the Tourbillon "Pour le Mérite," the Saxonia, and the Arcade. Interestingly, none of these models feature a simple three-hand round movement, something that is essential for any watch manufacturer. Perhaps Blümlein intentionally dropped the "normal watch" model to differentiate itself.
However, he understood that differentiation alone would not bring great success. In fact, in a 97 interview with Uhren Austria magazine, Blümlein said:
"The sophisticated 'banker's watch' with a small seconds at 6 o'clock has a future."
The sophisticated banker's watch he described was the "1815," released in 95. It was powered by the round L941.1 movement. Furthermore, the case back was finally changed to a transparent one (the earliest models had a solid back), allowing the watchmaker to view the excellent movement. It was only after this that A. Lange & Söhne began to display its movements.
Although this three-hand, manual-winding watch did not attract as much attention as the Lange 1 or Datograph, the 1815 would go on to become A. Lange & Söhne's "bread and butter" and grow into a major collection that supported the company's foundation.
