Object description

Case and Dial

The Patek Philippe Ref. 4936G is housed in an 18K white gold two-body case with a diameter of 37 mm and a thickness of 11.5 mm. The design includes concave lugs and a concave bezel and crown, which are set with a total of 170 diamonds weighing approximately 1.00 carat. The case back is transparent, secured by screws, and utilizes sapphire crystals on both sides.

The dial is constructed from mother-of-pearl, featuring applied luminous white gold radial Roman numeral indices. It includes a secondary minute/seconds track on the periphery. The calendar functions are displayed via two subsidiary dials for the day of the week and the month, while a date aperture is located at 6 o'clock, alongside a moon phase indicator. The time is read via luminous white gold feuille hands.
