Watch Review | Patek Philippe 7071R

The Patek Philippe 7071R is an extremely alluring ladies timepiece ,a squarish with rounded corners and soft sides that make it look and feel like it was designed for the modern lady. Inspired by the Art Deco watches which comes in at a width of 35mm and a length of 39mm, with two dial choices available , silver opaline or opaline black dial with guilloched flame pattern. The black dial has the added intricacy and beauty of the guilloche, while the silvery white dial is simple, elegant and readable at the same time. Two chrono subdials are slightly offset beneath the center axis of the large leaf shape hour and minute hands, for the small seconds and 30 minute counter. Indices are roman numerals , brown for the white dial and applied 18k rose gold for the black dial. The subdial details follow the same color choices. The case only comes in 18k rose gold , and has sapphire crystal front and back .

Inside this very alluring timepiece is the Calibre CH 29-535 PS (with 6 new patent behind it), a traditional column wheel controlled mechanism , which took more than half a decade to develop .The new mechanism offers a large chronograph hand , a seconds sub dial and an accurate jumping 30 minute counter. The Calibre CH 29-535 PS has a power reserve of 65 hours in regular operation and will go up to 58 hours if the chronograph is activated.

The six patents behind CH 29-535 PS:

• An optimized tooth profile - eliminates the risk of hand jump in both directions when starting a measurement , limits chronograph hand quiver, increase energy transmission efficiency , and reduces friction as well as wear in the movement.
• Improved penetration adjustment between the clutch and the chronograph wheel - this new system enables a more precise adjustment of the penetration between the clutch and the chronograph wheel.
• Improved synchronization between the clutch lever and blocking lever - This simplifies and improves the precision adjustment of the control sequences because watchmakers only has to adjust one point instead of two as was the case in the past.
• A pierced - out minute - counter cam - to prevent abrupt blocking in response to the reset command and therefore considerably reduced hand quiver.
• Self setting return to zero hammers - This makes it unnecessary to mechanically adjust the minute hammer function and thus increase the reliability of the mechanism .
• Hammers pivoted between jewels - This assures that the hammers remain precisely aligned in the vertical direction and improves the smoothness of their rotation.
