Blancpain Fifty Fathoms 5015-1144-52

The Blancpain Fifty Fathoms Automatique, reference 5015-1144-52, is a highly regarded variation of the modern Fifty Fathoms line, distinguished by its captivating blue flinqué dial and matching sapphire bezel. Introduced as a boutique-exclusive edition, its historical context places it within the 21st-century trend of luxury sports watches with vibrant dial colors. This reference is significant as it broadened the appeal of the typically black-dialed Fifty Fathoms, offering a more expressive and less utilitarian option while retaining all the professional diving capabilities. The watch is presented in the standard 45mm stainless steel case with polished finishing, providing a brilliant contrast to the deep blue hues of the dial and bezel. Like its counterparts, it features the iconic domed scratch-resistant sapphire bezel insert with luminous markings. At its core is the robust and reliable in-house Caliber 1315. This automatic movement is celebrated for its substantial 120-hour (5-day) power reserve, a result of its three series-coupled mainspring barrels, and its use of a silicon balance spring for enhanced anti-magnetic properties. The combination of its stunning aesthetics, impeccable build quality, and a high-performance movement makes the 5015-1144-52 a standout reference in the extensive Fifty Fathoms catalog. It is most commonly paired with a blue sailcloth strap to complete its maritime theme.
