That’s a good analogy! Yes indeed, they are quite interesting and scarce. I actually like the slight shudder of the seconds hand, as a sign of its design and relative rarity.

i love this indirect-seconds caliber, bolt-on complications were like hot-rodding watches. didn’t know they had a shudder issue, but still would pick it over the 27sc.

What a crazy rabbit hole of scholarship- very cool. Apart from the shudder was there any legitimate reason to believe it was less reliable due to the indirect drive?

Also, regarding the 4-digits on case + caseback matching, is this just a fun quirk that you’ve identified or is there something else consistent across all examples (other than being steel)? It’s not the older movement as I think you said 2/3 had it… I’m perhaps being thick here.
