Hi, Jeff,
Thanks for the further thoughts. In reading your comments, I'm not sure we were saying anything different, though it is always nice to read things from another perspective or with different wording, something akin to reading or discussing the same topic in another language....subtle nuances do bubble to the surface.
(Ref my level 2b / 2c in what would constitute a (serious) tourbillon today.)
Regarding semantics, I agree that a "tourbilllon" is not a "complication" in the classic definition, but you know as well as I do that there are many many fine hairs to split if we decided that's what we wanted to do.
Is a small second a complication, petite or otherwise?
What constitutes a Grand Complication vs a grand complication?
Would a tourbillon count as a "complication' in the classic definition of a Grand Complication and its necessary minimum number of complications (often a rattrapante chronograph, repeater and perpetual, though one must distinguish, then, between a Triple Complication vs a Grand Complication; and yes, I am aware that in some cases there are those that would argue no, a tourbillon would NOT count as one of the requisite complications to qualify for a Grand Complication; others would...)
What level complication is a perpetual, especially today when modules can add a perpetual calendar to a base movement for not much money and not much watchmaking skill?
I agree it is always a good idea to be rigourous in one's use of terms and consistent in which "reference" one adheres to.
Is a Jumbo (specific model name) the same as a jumbo? (generic adjective describing a model the same size or larger than a Jumbo but not specifically referred to as such)
Berners, et al, are good starting points for updates and modernizations...
On the other hand, I did clarify at least twice in my original post that it was a knee jerk, unedited "stream of consciousness" mind dump so I hope you'll forgive any fast and looseness with specific terminology between reference standard semantic rigour and common idiomatic usage...
;-)
Always a pleasure to read you, Jeff...hope all's well.
