Сообщение от Laureus
В той усеченной документации как раз описывается работа двух барабанов -- система вкратце, ручной завод, автоподзавод и их работа при отдаче энергии. Отдача идет сначала от второго барабана ("автоматический") непосредственно на центральное колесо. И только при равенстве завода с первым барабаном ("ручным") происходит одновременная отдача....

"The two barrels are wound sequentially.
The barrel without the slip-spring (the socalled
“hand-winding barrel”) is wound first.
As soon as it’s full, winding energy is conveyed
only to the barrel with a slip-spring (the
“self-winding barrel”). In the opposite direction,
the self-winding barrel first discharges
its store of energy directly to the center
wheel. If the stockpile of energy is equal in
both barrels, then the two barrels discharge
their reservoirs of energy at the same time.
Omega claims a 60-hour power reserve for
this movement, and our test confirmed that
this is no exaggeration. The barrels are coated
with DLC (diamond-like carbon), which means
that they function with little loss of energy and
practically no wear-and-tear. There is enough
power available in the barrels for a long power
reserve, but none of the energy stored there
is squandered to compensate for any shortcomings
in the construction. The way that energy
is budgeted in Caliber 8500 guarantees
that the pressure exerted on the individual pivots
is always less than 300 N/mm2. That’s a
sensible level that significantly extends the
lifespan and simplifies servicing.
The superlative quality of all components
in the movement is borne out by the excellent
rate results. We discovered “plus” values
(gain) in all six tested positions, and only minimal
differences in amplitude, not only when
fully wound, but also after 24 and 39 hours.
Caliber 8500 also performed well in the obligatory
wrist test, where we measured a gain of
just two seconds per week. Marc-André
Miche, upon whose desk at Omega the passing
buck stops where technical developments
are involved, told this writer that he would
have been satisfied with a “plus” value of two
seconds per day or one minute per month.
Miche can rest easy, because this caliber can
do even better."
