Encased in polished 18K white gold, the 40 mm case provides a contemporary presence while showcasing the understated elegance associated with the Grand Complications collection. A sapphire crystal caseback offers a view of the meticulously finished self-winding mechanical movement, highlighting the Geneva craftsmanship, intricate architecture, and refined decoration expected from Patek Philippe. The combination of precious-metal construction, an innovative metallized sapphire crystal dial, and an advanced retrograde perpetual calendar complication gives the 6159G-001 an unmistakably sophisticated character.
