Rooted in Blancpain’s pioneering heritage since the first Fifty Fathoms launched in 1953, the 5010 45mm redefines luxury dive watches with its robust design and exceptional performance. The 45mm case, crafted from corrosion-resistant grade 23 titanium or 18K rose gold, undergoes meticulous satin brushing and polishing, creating a refined texture that resists scratches and wear. It retains iconic Fifty Fathoms DNA, including a cambered scratch-resistant sapphire crystal and a unidirectional rotating bezel with a ceramic insert and luminescent scale, ensuring precise dive timing even in low-light underwater environments.

The dial exudes understated luxury with a sunburst finish, paired with luminescent Arabic numerals and broadsword hands coated in Super-LumiNova X1 for superior readability at great depths. A practical date window enhances daily functionality, while the open-worked rotor design on the movement pays homage to the original Fifty Fathoms, revealing the 18K gold accent beneath. The watch’s夜光 performance stands out as industry-leading, with multi-layer fluorescent coating delivering bright illumination in dark conditions.

At its core lies Blancpain’s in-house Cal. 1315 automatic movement, a benchmark of reliability and precision. Equipped with three mainspring barrels, it offers an impressive 120-hour (5-day) power reserve, operating at 28,800 vibrations per hour. The silicon balance spring ensures anti-magnetism and shock resistance, while exquisite decorations including Côtes de Genève and snailed bridge tops are visible through the sapphire exhibition case back.

Versatile and durable, the 5010 45mm boasts 300-meter water resistance, suitable for professional diving and daily activities. It comes with multiple strap options—sailcloth, Tropic rubber, NATO, or titanium bracelet—all featuring a secure folding clasp. Whether for deep-sea exploration, business meetings, or casual wear, this timepiece seamlessly adapts to diverse scenarios, embodying Blancpain’s philosophy of blending professional performance with timeless elegance.
