Description
One of the ever made smallest pin lever movements is the Baumgartner caliber 930. According
to Flume, it has got a diameter of only 6 3/4 lignes; if you measure it, it's exactly 7 lignes.
With its construction, it very much reminds of small anchor lever movements, such as the
ETA 2412.
With seventeen jewels, among them a number of deck jewels, which are fixed in kind of
chatons, with a coupling winding mechanism and partially polished plates, it is certainly
among the best Baumgartner pin lever movements.
As usual on Baumgartner, this movement does not have a minute wheel, but the minute- and
hour hands are indirect driven by the mainspring barrel.
