A modern evolution of a true dive-watch icon, the Blancpain Fifty Fathoms Grande Date ref. 5050-12B30-B52A combines professional-grade performance with refined haute horlogerie engineering. Crafted in lightweight titanium and powered by Blancpain’s in-house Calibre 6918B, this timepiece is built for extreme conditions while maintaining exceptional everyday legibility and comfort.

The bold 45mm titanium case houses a deep black dial with luminous Arabic numerals and a prominent large date display, ensuring instant readability both above and below the surface. With a 300-meter (30 ATM) water resistance, sapphire crystal, and unidirectional rotating bezel, this watch remains faithful to the Fifty Fathoms’ military diving heritage—while introducing contemporary technical sophistication.

Key Complications & Technical Highlights

Secured Movement

Blancpain’s secured movement system protects the delicate internal components from accidental damage during time and date adjustments. This innovation enhances long-term reliability and preserves chronometric precision—an understated hallmark of Blancpain’s craftsmanship.

Large Date Complication

The oversized date aperture uses two separate discs (tens and units), allowing for superior legibility and smoother transitions. This advanced mechanism reflects true high-end watchmaking, offering both functionality and visual balance on the dial.
