Collectors prioritize this reference for the Caliber RMCC1, a manual-wind movement weighing only 9.5 grams that integrates a tourbillon with a split-seconds chronograph and power reserve, torque, and function indicators. The case utilizes Carbon TPT, a material composed of layered carbon fibers that provide high rigidity and a distinct damascene pattern. Due to its technical complexity and extreme rarity, the RM 050 typically commands secondary market prices in the mid-to-high six-figure range, often exceeding $800,000 depending on provenance. A notable production detail is the movement’s baseplate and bridges crafted from grade 5 titanium, which underwent extensive validation tests to ensure shock resistance during high-impact racing conditions.", "score": 205}, {"slug": "a-lange-sohne-datograph-405", "brand": "A.

The movement features a flyback chronograph, a jumping minute counter, and a signature oversized date display. The dial is crafted from solid silver with a black galvanized finish and rhodiumed gold appliques. On the secondary market, this reference typically trades in the low-to-mid six-figure range, generally between $100,000 and $130,000 depending on condition and provenance.

The dial features traditional hand-guilloché patterns, blued steel pomme hands, and a leap year indicator integrated into the month sub-dial. The platinum variant is rarer than the yellow gold versions and is distinguished by its weight and silvered solid gold dial. On the secondary market, the 3050 in platinum typically trades between $25,000 and $35,000 depending on the presence of the original box and papers.

Collectors prioritize this reference due to its oversized dimensions, often measuring approximately 44mm to 52mm in length, which distinguishes it from standard Baignoire models. The watch typically features a manual-wind Jaeger-LeCoultre caliber or a Cartier-signed movement. Key design elements include the elongated oval case, a white or silvered dial with Roman numerals, and \"London\" hallmarks on the case back. Due to limited production numbers during the London era, these pieces are rare. On the secondary market, prices generally range from $40,000 to $80,000, though exceptional examples have reached higher.
