Prestige & Value
The Patek Philippe Ref. 6159G-001 is a striking combination of tradition and innovation. Its retrograde perpetual calendar offers a mechanically theatrical display—particularly the sweeping date hand that instantly returns to 1 at month’s end—while its semi-transparent sapphire dial gives a peek into the movement’s inner workings.
The hobnail guilloché on bezel and caseback echo Patek’s historic motifs but recontextualized in a modern frame. :contentReference[oaicite:16]{index=16}
As a newly introduced reference (2025), it stands out in the Grand Complications line, likely to be sought after by discerning collectors for its unique dial treatment and mechanical mastery.
