Unworn Blancpain Fifty Fathoms Bathyscaphe Quantième Complet Phases de Lune, Stainless Steel, 43mm, Ref# 5054-1110-B52A, box and papers

The Blancpain Fifty Fathoms Bathyscaphe Quantième Complet Phases de Lune Ref# 5054-1110-B52A masterfully fuses robust dive-watch engineering with refined horological complications. Housed in a 43mm brushed Stainless Steel case, this new/unworn timepiece features a metallic grey sunray dial that radiates understated elegance beneath the surface. Bold polished Steel hands and applied index markers—each filled with luminous material—ensure excellent legibility in low light. The dial displays a complete calendar, with day and month windows nestled under 12 o'clock, a moonphase aperture gracefully positioned at 6, and a central red-tipped hand tracking the date around the dial's perimeter. Hidden under the lugs, the ingenious calendar corrector buttons can be adjusted without tools, preserving the sleek profile of the case. The unidirectional bezel, crafted from brushed steel and filled with scratch-resistant black ceramic and Liquidmetal® numerals, is built for enduring use, while a luminous dot at 12 adds practical dive functionality. Powered by the in-house automatic Caliber 6654.P, this watch offers a 72-hour power reserve. Thanks to its 35 jewels and a nonmagnetic silicon balance spring that resists magnetism the mechanism is extremely resistant to corrosion, wear and natural aging. Finished with a black sailcloth strap backed with rubber and secured by a tang buckle, this Bathyscaphe arrives in a rugged Peli water-resistant case, ready for exploration in both depth and detail. With 300m water resistance and a transparent case back, a luxury diver’s as technically impressive as it is visually captivating.
