Unworn Blancpain Fifty Fathoms Grande Date, Titanium, 45mm, Ref# 5050-12B30-B52A, box and papers

Introducing the unworn Blancpain Fifty Fathoms Grande Date 45mm, Ref. 5050-12B30-B52A — a professional-grade diving instrument rooted in one of horology’s most historic underwater legacies. The name “Fifty Fathoms” references its original depth rating, with one fathom equaling six feet — a direct nod to its maritime heritage. The imposing 45mm brushed titanium case, measuring 16.27mm in thickness, delivers exceptional strength while maintaining remarkable lightness on the wrist. Its black sunray-finished dial radiates subtle depth, complemented by applied hour markers and hands filled with luminous material for optimal legibility in low light and underwater conditions. A prominent double-window Grande date display at 6 o’clock ensures immediate readability without compromising dial symmetry. Encircling the dial is a unidirectional rotating bezel featuring a luminous diving scale, engineered for precise elapsed-time measurement. The bezel is capped with sapphire crystal, providing superior resistance against scratches and impacts. A scratch-resistant sapphire crystal also protects the dial, while the transparent case back reveals the mechanical architecture within. At its core beats the Blancpain in-house Caliber 6918B, equipped with a silicon hairspring for enhanced resistance to magnetism and improved chronometric stability. Operating at 28,800 vibrations per hour and composed of 44 jewels, the movement offers an extraordinary 8-day (120-hour) power reserve, underscoring Blancpain’s technical mastery. The watch is presented on a rugged blue canvas strap with rubber lining, secured by a titanium pin buckle for durability and comfort. Water-resistant to 300 meters (1000 feet), this Fifty Fathoms is built for serious diving conditions. It is delivered in a genuine Peli water-resistant carrying case (9" x 7" x 4"), reinforcing its professional, expedition-ready character. A true modern dive watch icon, the Fifty Fathoms Grande Date combines advanced engineering, extended autonomy, and uncompromising underwater performance.
