Lange’s new movement crop this year included the new 1815 Up/Down
As I mentioned in Tuesday’s post, Lange introduced several new movements this year. The superb and magnificent 1815 Rattrapante Perpetual Calendar, the new Grande Complication, and today I feature a refreshed 1815 Up/Down.
This is a reissue of an old favourite…the original 1815 Up/Down…which created a small sensation as Lange managed to squeeze in the power reserve mechanism into the same case as the regular 1815…and it was not that the regular 1815 had a lot of room to play with inside the case. The case measured then 36mm. By today’s reference, a very small case size.
The new Up/Down, or Auf/Ab in German is refreshed with a new movement, and a larger case size…still a rather modest 39mm, with a thickness of 8.9mm. 
And the beautiful movement
