The Blancpain Fifty Fathoms Automatique 5007-12B40-98S showcases Blancpain’s fusion of dive-grade durability and refined aesthetics. Encased in satin-brushed Grade 23 titanium, this 38.2 mm timepiece delivers a lightweight yet robust presence on the wrist. Its rich blue sunburst dial, encircled by a matching unidirectional sapphire bezel, ensures outstanding legibility and vibrant depth both above and below the surface.

Within beats the in-house ultra-slim Caliber 1153 automatic movement, offering a mighty 100‑hour power reserve and outfitted with a silicon balance spring for superior anti-magnetic performance. A sapphire crystal case back provides a glimpse into the finely finished movement—an homage to Blancpain’s craftsmanship.

Water-resistant to 30 bar (300 metres), and fitted with a matching titanium bracelet secured by a folding clasp, the 5007-12B40-98S seamlessly blends ocean readiness with everyday elegance.
