The 5738/50P-001 is built on the same ultra thin automatic caliber 240, but distinguished by its hand engraved platinum case, where intricate patterns are carved entirely by artisans. The dial is crafted in blue gold, providing depth and contrast while maintaining minimal visual interruption. The case dimensions follow the Golden Ellipse proportions, while the finishing extends beyond traditional movement decoration to the exterior surfaces. The sapphire case back reveals the micro rotor movement, finished to the highest standards.

This watch operates at the intersection of horology and decorative art. The engraving transforms the piece into something highly individual, ensuring that no two examples carry the exact same character. It appeals to collectors who value rarity and artisanal work as much as mechanical precision.

Reference & Dial Context

The 5738/50P-001 is a unique 50th-anniversary reference, rather than another dial variation of the standard 5738P-001 or 5738R-001. Its black enamel and hand-engraved dial was specifically created for the 2018 anniversary edition and was limited to 100 watches.
