Introducing Patek Philippe Grand Complications (ref. 6300/400G-001), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: measuring 47.4 mm in diameter, with a thickness of 16.07 mm, defined by a round silhouette, paired with a gem-set bezel. The caseback is double dial, and the crystal is sapphire. At a glance, the dial balances texture and clarity: a black tone with guilloche finish, executed in yellow gold, framed by arabic numerals hour markers, and poire hands. At its heart beats a proven engine: the 300 GS AL 36-750 QIS FUS IRM caliber. First released in 2022. With considered ergonomics, it feels composed during extended wear. Brushed and polished elements play with light to emphasize crisp geometry. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
