No disagreements, Covenant. Does this mean a Citizen with the 0100 movement is in your future?The more time I spend in this hobby, the less enchanted I am with purely mechanical watches in general. I think the main sticking point I have is that I, perhaps irrationally, equate accuracy with quality.
The persuit of accuracy is what makes horology interesting to me. Advancements like the tourbillion that attempt to negate positional errors, or constant force escapements that improve isochronism, or inventions like the Daniel's coaxial escapement that reduce friction. I find the "arms race" if autonomous accuracy appealing from an engineering perspective.
So spring drive is inherently seductive for offering quartz timekeeping performance without losing the romance of mechanical. But truth be told, what is "ruining" mechanical watches for me is high accuracy quartz. Once one gets over the subconscious bias against the 1-second tick, the sheer coolness of pushing the envelope of accuracy to the limit sets in. A second hand that meets all the markers dead on without any wobble is as good a look as a sweeping hand, IMO (although not as impressive as SD's glide).
Personally, while I appreciate (and value) accuracy, I find obsessing on it too much can, for me, detract from the enjoyment of my watches. I wear each of my watches for 5-7 days straight, so as BrianBinFL noted in post 4, I can live with their inaccuracies (my least accurate watch is a Stowa Antea B2B, +14 a day, my most accurate, my Credor handwinding Spring Drive, +0.3 a day). But there is definitely something satisfying when I wear a watch for a week and find a total deviation of under 10 seconds (my Damasko DA46 with an elabore 2836-2 movement is +6 after 9 days |>).
