The Blancpain Fifty Fathoms X Fathoms, reference 5018 1230 64A, represents the pinnacle of mechanical dive watch engineering. Housed in a bold 55.6 mm titanium case, this timepiece is purpose-built for professional divers who demand uncompromising performance. Its striking black dial features highly legible luminous markers and hands, surrounded by a unidirectional sapphire bezel for secure dive timing. Engineered for a depth rating of 300 meters, the X Fathoms integrates cutting-edge functionality into a visually commanding design, staying true to Blancpain’s pioneering spirit in underwater watchmaking. At the heart of the watch is the Caliber 9918B, an automatic movement derived from the robust Caliber 1315. This complex mechanism features a mechanical depth gauge capable of measuring depths up to 90 meters, with precision scaling for both 0–15 meters and 0–90 meters. The gauge employs a high-tech amorphous metal membrane for sensing pressure changes, transmitted through a rack-and-pinion system for real-time readings. Additional diving features include a retrograde 5-minute decompression timer, maximum depth memory with a secured reset system, and a helium escape valve—making this a serious tool for deep-sea exploration. Completing the X Fathoms is a unique black rubber strap composed of 14 articulated segments, engineered to flex with wrist movement and allow optimal water flow to the depth sensor. The titanium folding clasp ensures secure wear in all underwater conditions. This timepiece is not just a statement of luxury—it is a professional-grade diving instrument that pushes the limits of horological innovation. As the most complex mechanical dive watch ever created by Blancpain, the X Fathoms is a true testament to the brand’s leadership in marine timekeeping.
