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
st
cen-
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, their upper sides straight-
grained, and the rattrapante clamps superbly
polished. Gleaming and matt surfaces alternate,
accentuated with gold-filled engravings and spar-
kling ruby-red jewels. These finishing touches re-
flect the pinnacle of watchmaking 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 +2 to -3 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
genuine enamel dial stands out with an intensely
rich black and excellent legibility.
