Housed in an 18k yellow gold case measuring 46.4×36 mm, the reference 5013J-010 from Patek Philippe's Grand Complications collection carries an 18k yellow gold bezel and a screw-locked crown, offering water resistance to 30 metres. A sapphire crystal protects the black dial, keeping the overall presentation clean and legible.
Power comes from an automatic movement, delivering reliable performance within this distinctly shaped case. The watch rides on a leather strap secured by a folding clasp, lending a classic and comfortable feel on the wrist.
This is a notable example from one of watchmaking's most storied Grand Complications lines, combining the warmth of yellow gold with the bold contrast of a black dial in a format that stands apart from conventional round-case offerings.
