Case and Dial Design

The Patek Philippe Ref. 5970G is housed in a three-body, 18K white gold case, measuring 40 mm in diameter and 13 mm in thickness. The design incorporates a polished finish with a concave bezel and curved, fluted lugs. The case features a transparent screwed-down back, which allows for viewing of the movement, complemented by sapphire crystals on both sides. A secondary solid 18K white gold case back is also provided with the set. The matte silver dial displays a comprehensive array of information. It includes applied oxidized white gold faceted baton indexes and matching feuille hands. Chronograph functionality is provided via a 30-minute register and an outer tachometer with a 1/5th seconds scale. Perpetual calendar indications are presented through apertures for the days of the week, months, and moon phases, alongside subsidiary dials for 24-hour time and leap year cycles. The watch is water-resistant and fitted with an 18K white gold Patek Philippe deployant clasp, as described in the official lot documentation. The dial retains a clean, organized layout despite the inclusion of multiple astronomical and timing functions.

Provenance and Accompaniments

This lot comprises the wristwatch along with its full set of original accompaniments. These include the original mahogany fitted box, an instruction manual, a setting pin, and a blank Certificate of Origin. The watch also includes the additional solid 18K white gold case back, which can be interchanged with the transparent sapphire display back. The entire object is reported as being in "as new" condition, as indicated by the grading system applied by the auction house. The lot records provide the specific case number 4332382 and movement number 3048031, which are also recorded on the internal documentation provided with the timepiece.

Movement and Mechanical Details

The timepiece is powered by the Caliber 27-70Q, a manual-wind movement stamped with the Seal of Geneva. The movement contains 24 jewels and utilizes a straight-line lever escapement. The balance is a Gyromax type, adjusted for heat, cold, isochronism, and 8 positions, equipped with a self-compensating, free-sprung Breguet balance spring. Because the watch remains in its original sealed factory packaging, the mechanical operation has not been tested, and the movement remains inaccessible for physical inspection during the auction process.
