Blancpain’s 2024 ceramic Bathyscaphe Quantième Complet Phases de Lune pairs a black ceramic case with a matching bracelet and a complete calendar with moon phase. The blue-dial version is reference 5054 0140 01S; launch coverage also lists a green-dial version, reference 5054 0153 01S. This is a complete calendar—not an annual or perpetual calendar—so it needs adjustment as the months change.
What the ceramic Bathyscaphe calendar is
The watch is part of Blancpain’s 2024 ceramic Bathyscaphe releases, alongside three-hand automatic and flyback chronograph models. Its defining combination is a black ceramic case and bracelet, a sunray dial, and a complete-calendar display with moon phase. Fratello lists the blue model as reference 5054 0140 01S and the green as 5054 0153 01S in its launch coverage.
On the dial, day and month appear in apertures, the date is indicated by a central hand, and the moon phase sits at six o’clock. The calendar is not annual or perpetual: it does not automatically account for differing month lengths, so the indications require adjustment as needed. Hodinkee’s launch report makes this distinction explicit.
Case, movement, and specifications
| Specification | Reported details |
|---|---|
| Case | Black ceramic; 43.6 mm diameter, 49.5 mm lug-to-lug, and 14.1 mm thick, according to Fratello’s 2024 launch specifications |
| Water resistance | 300 m / 30 bar, according to Fratello’s 2024 launch specifications |
| Crystal and back | Sapphire crystal; ceramic screw-in caseback with sapphire display window, according to Fratello |
| Bezel | Ceramic insert with Liquidmetal markings, according to Fratello |
| Movement | Automatic caliber 6654.P; also styled 6654.P4 in Hodinkee’s report. It supports manual winding, has 28 jewels, and is reported at 28,800 vibrations per hour |
| Power reserve | 72 hours, as reported in Fratello’s launch specifications |
| Calendar and moon phase | Day and month apertures, central pointer date, and moon-phase display at six o’clock |

The 43.6 mm diameter and 14.1 mm thickness give the watch a substantial presence; the reported 49.5 mm lug-to-lug measurement adds useful context when considering how it may span the wrist. Those dimensions describe the case, not a guarantee of fit for every wearer.

The matching ceramic bracelet
The bracelet is made to match the black ceramic case and measures 23 mm wide. Blancpain describes its patented link system as using cam-shaped pins. The brand also says its ceramic is nearly five times harder than stainless steel and 25% lighter; those are manufacturer material claims, not independent comparative test results. Blancpain’s release describes firing above 1,400°C and manufacturing shrinkage as part of the production process. See the official Blancpain announcement.
Blancpain and Swatch Group describe the bracelet as an option for this complete-calendar model and for some other ceramic Bathyscaphe references, including three-hand and flyback-chronograph versions. That does not establish compatibility with every Bathyscaphe. Check the exact watch reference and bracelet fitment with Blancpain or an authorized retailer before ordering.

How it compares with the other 2024 ceramic Bathyscaphes
The three models share a reported 43.6 mm case diameter, 300 m water resistance, and 23 mm lug width, but their thickness, power reserve, and complications differ. The values below are reported in Fratello’s 2024 launch specifications; the movements and reserves are specific to each configuration.
| Model | Complication / movement | Reported thickness | Reported power reserve |
|---|---|---|---|
| Three-hand automatic | Caliber 1315 | 13.83 mm | 120 hours |
| Flyback chronograph | Caliber F385 | 15.25 mm | 50 hours |
| Complete calendar and moon phase | Caliber 6654.P | 14.1 mm | 72 hours |
The calendar model’s extra displays distinguish it from the simpler three-hand watch, while the chronograph is thicker in the launch specifications. For the calendar model, launch coverage lists a ceramic bracelet, sail-canvas strap, and NATO-style strap. Do not assume that straps or bracelets interchange across all references without checking fitment.
