The Blancpain Fifty Fathoms Bathyscaphe Quantième Complet Phases de Lune, reference 5054-0130-B52A, is a masterful expression of Blancpain’s fusion of advanced mechanical watchmaking and contemporary luxury design. Housed in a 43.6 mm satin-brushed black ceramic case, the watch presents a commanding yet refined profile on the wrist. Its Sunburst Black Dialis harmoniously balanced with applied luminous hour markers, a complete calendar display (day, date, month), and a beautifully detailed moon phase complication positioned at 6 o’clock. The unidirectional rotating bezel, also crafted in ceramic with a Liquidmetal® insert, not only reinforces the watch’s diving functionality but also contributes to its ultra-modern, scratch-resistant appearance. At the heart of this timepiece is the Blancpain Caliber 6654.P.4—an in-house, self-winding mechanical movement operating at 28,800 vibrations per hour. This 321-component caliber features dual barrels delivering a robust 72-hour power reserve and incorporates a silicon balance spring for improved magnetic resistance and long-term chronometric stability. The complication-rich movement drives the complete calendar and moon phase functions with precision, while maintaining user convenience through under-lug corrector pushers that allow quick adjustments without marring the case’s sleek lines. A sapphire crystal case back offers a view of the beautifully decorated movement, including traditional Côtes de Genève finishing and a polished gold rotor engraved with the Blancpain logo. Combining technical sophistication with high-end finishing, this model epitomizes Blancpain’s commitment to both functional performance and discreet elegance. With 300 meters of water resistance, it upholds the Fifty Fathoms legacy as a true dive watch, yet it wears comfortably in formal settings thanks to its lightweight ceramic case and refined proportions. Paired with a durable black sail-canvas strap and a secure pin buckle, the 5054-0130-B52A is a luxury timepiece that caters to discerning collectors who value mechanical complexity, innovation, and timeless design in equal measure.
