Details

A masterful blend of fine watchmaking and diving precision, the Blancpain Bathyscaphe Chronographe Flyback 5200-3640-NAOA brings a bold yet elegant presence to the Fifty Fathoms collection. This exceptional timepiece is crafted in sedna gold, an exclusive rose gold alloy enhanced with palladium and copper for long-lasting warmth, color stability, and corrosion resistance. At 43.6mm, the case maintains a commanding wrist presence while retaining the clean, functional lines that define the Bathyscaphe aesthetic. The dial is finished in a rich sunburst blue, catching the light with subtle radiance and echoing the deep hues of the ocean. It features three recessed chronograph subdials, a discreet date window between 4 and 5 o’clock, and Super-LumiNova® hands and hour markers to ensure optimal readability in all conditions, from boardroom to seabed. The dial is framed by a unidirectional blue ceramic bezel filled with Liquidmetal®, an innovative, scratch-resistant alloy that ensures both aesthetic sharpness and functional durability. Powering the watch is the sophisticated Blancpain Caliber F385, an in-house automatic flyback chronograph movement beating at 5 Hz (36,000 vibrations per hour). This high-frequency movement allows for precise timekeeping and supports flyback functionality, enabling the chronograph to reset and restart instantly with a single push of the button. It incorporates a column wheel and vertical clutch for smooth chronograph engagement and long-term mechanical reliability. The movement is showcased through the sapphire crystal caseback, revealing fine finishing, Geneva stripes, and a gold rotor engraved with the Blancpain logo. Completing the timepiece is a blue NATO strap, which gives it a sport-luxury edge while offering lightweight comfort and secure wear during high activity. With 300 meters of water resistance, this model stays true to its Fifty Fathoms lineage as a robust, fully capable diving instrument. The Blancpain Bathyscaphe Chronographe Flyback in sedna gold is a watch that seamlessly merges heritage and innovation — equally suited for adventure, elegance, and everyday wear.
