Peerless Finissage - Patek Philippe 5370 Mode D'emploi

A movement for the future
Aptly expressing Patek Philippe's philosophy, the
manufacture caliber CHR 29-535 PS melds tradi-
tion with innovation. The manually wound watch
with column-wheel control and wheel clutch fea-
tures all of the key hallmarks of the classic caliber
architecture but with many patented technical
innovations is decidedly rooted in the 21
tury. It ranks among the most progressive move-
ments of its kind. The optimized chronograph
mechanism is paired with innovations for the
split-seconds function, including the isolator for
the rattrapante hand lever that disconnects the
split-seconds wheel from the chronograph wheel
as soon as a lap time is stopped. This prevents un-
necessary friction and eliminates any degradation
of the amplitude of the balance. The rattrapante
lever with the ruby roller between two flat con-
tact shoulders assures that the chronograph and
split-seconds hands are perfectly congruent when
superposed.

Peerless finissage

As all Patek Philippe movements, this caliber
stands out with lavish decorations that can be
admired through the display back. Most steel
parts are round-chamfered and polished, their
upper sides straight-grained. Gleaming and matt
surfaces alternate, accentuated with gold-filled
engravings and sparkling ruby-red jewels. These
finishing touches reflect the pinnacle of watch-
making artistry and are mandated by the Patek
Philippe Seal, deemed the strictest set of quality
directives in the watch industry. It also specifies
the rate accuracy with a maximum deviation of -3
to +2 seconds per day.

Custom-cased in platinum
The stunning looks of the meticulously crafted
Ref. 5370 are absolutely on par with its impres-
sive inner life. The platinum case is graced with
subtle rounds and cambers in balanced propor-
tions, two oval chronograph pushers at 2 and 4
o'clock, and, between them, an elegant turban-
style crown with an integrated split-seconds but-
ton. The same attention to detail was devoted to
the gently curved strap lugs with the decorative
cabochons that adorn their ends. Created with ar-
tisanal techniques rooted in a grand tradition, the
Grand Feu enamel dial stands out with an intensely
rich blue and excellent legibility.
