The Blancpain Bathyscaphe Quantième Complet Phases de Lune Ref. 5054-1110-NABA offers a rare fusion of elegant complication and robust diving performance. Crafted in stainless steel, the 43mm case exudes a clean, modern feel while remaining true to the Bathyscaphe’s professional dive heritage. This model stands out in the Fifty Fathoms collection by integrating a complete calendar and moon phase complication, bringing Blancpain’s watchmaking pedigree to the forefront of a sporty, utilitarian design. The dial features a rich meteor grey sunburst finish, giving depth and texture to the elegant layout. A day and month window is positioned just below 12 o’clock, while a central pointer hand tracks the date around the outer edge of the dial. At 6 o’clock, a moon phase aperture adds a poetic and functional touch to the display. The watch also includes Super-LumiNova® coated hands and indexes for optimal visibility in low light, framed by a unidirectional ceramic bezel in matching grey for precise dive timing. Powered by the Blancpain Caliber 6654.P, this automatic movement features a 72-hour power reserve, a silicon balance spring for magnetic resistance, and a beautifully finished rotor visible through the sapphire caseback. Paired with a black NATO strap, the watch is both rugged and comfortable for everyday wear, offering a secure fit and casual style. With 300 meters of water resistance, this Bathyscaphe delivers serious dive-watch performance while showcasing Blancpain’s mastery of horological complications.

Care & Maintenance

Clean regularly with a soft cloth. Avoid exposure to chemicals, extreme temperatures, and magnetic fields. Store in a safe, dry location when not in use.
Mechanical watches should be serviced every 3-5 years by a certified watchmaker to ensure optimal performance and longevity.
Water resistance varies by model. Check your watch's specifications and avoid exposing non-water-resistant timepieces to moisture.
Contact our service department immediately. Avoid attempting repairs yourself, as this may void your warranty and cause additional damage.
Wind gently and consistently. Stop when you feel resistance to avoid over-winding. Automatic watches wind through wrist movement during regular wear.
Minor time variations are normal. Mechanical watches typically vary ±15-30 seconds per day. If variation exceeds this range, professional adjustment may be needed.
Most watches allow date adjustment, but avoid changing the date between 9 PM and 3 AM when the date mechanism is actively changing to prevent damage.
Warranty terms vary by manufacturer and model. Contact us for specific warranty information and to understand what is covered under your timepiece's warranty.
