So maybe consider a simpler Richard Lange or an 1815. The one thing that irks me about the Richard Lange is the added thickness for only that tiny one mechanism that sticks out on the back of the movement. The story goes like this. Lange made the time-only Richard Lange movement and it worked well. But with the large central second hand at 21,600 vph vibrated noticeably in some people's eyes, some people complained that they could see the second hand vibrations at the outer radius. Thus, to smooth out those vibrations, Lange added gears on a small tower that stuck out and these gears acted like a "damper" to soften out those vibrations - basically using two "idler gears" that act as shock absorbers (I'm oversimplifying it, but that's the basic quick explanation). Unfortunately, this small module stuck out and looked like an afterthought - it probably was an afterthought judging by the story it was a last minute addition.
