November 5, 2009:

...being announced tonight at a big gala event in Paris. I am sure more info and pictures will follow.

Here are some unofficial specs.
Height - 5.35mm
Diameter - 29.6mm
Power reserve - 65hrs (58 hrs when chrono is engaged)

Patek Philippe decided to use this new completely in-house made manual
wind chrono caliber
for the first time in company history - in a ladies watch (model 7071)

While the introduction of this revolutionary caliber in a ladies watch is not something that a majority of
forum hopping WIS enthusiasts expected - it is a MAJOR point in the history of Patek Philippe.
With gradual elimination of Nouvelle Lemania ebauche based calibers (references 5020, 5070, 5970, 5004 etc),
and the introduction of a first in house automatic chrono in 2006 (CH 28-520 IRM QA 24H) in 5960P.....this was
something that many PP collectors were awaiting for a long time.

Ladies' Complicated Watches

The Ref. 7071R "Ladies First Chronograph" enriches the manufacture's collection of elegant and intricate
watches explicitly designed for feminine wrists. More and more women have discovered a penchant for
complicated wristwatches, especially those designed and crafted by Patek Philippe according to the finest
traditions of horological artistry. They are attracted to the functionality and seductive beauty of chronographs.
That is why Patek Philippe decided to initially launch its latest caliber with this attractive complication in
a woman's format. Ref. 7071R "Ladies First Chronograph": The first Patek Philippe wrist chronograph
to celebrate its debut as a model for ladies.
