In respecting the anonymity of the person who responded to my request pertaining to the “unfinished” hands on some Lange watches, here is what I learned:
Basically, the reasons behind the unfinished hands are quiet straightforward:
A) Lange does not manufacture their own hands (or cases) as this is not possible for a small manufacture that produces around 5000 watches a year- Lange is, first and foremost a movement manufacturer, and they excel at that.
B) The hands can’t be ordered finished- Given their thinness, finishing both sides has resulted in many cracking or breaking due to tight tolerances. The few that manage to pass the compliance run the risk of being a problem down the line, (and no one wants that). Its simply not viable to lose so many hands at such a large scale.
C) Lange does finish every movement component to the highest standard possible, in this instance they have full control over the manufacturing process and can adjust production accordingly - as this doesn't apply to the hands, proper finishing and functioning cannot be guaranteed.
A Lange timepiece is a product of craft and passion- the passion of the many talented and hardworking individuals who chose to pursue this craft. This, at least to me further shows how humane the art of watchmaking is and if anything makes me appreciate Lange even more.
Last but not least, Lange will at some point release an official statement to the issue at hand! (pun intended).
