The Rolex Cosmograph Daytona reference 116515LN-0055 is a 40mm luxury chronograph crafted from 18k Everose gold, a proprietary rose gold alloy developed by Rolex to preserve its luster over time. This model is distinguished by a meteorite dial, which is cut from natural extraterrestrial material salvaged from the Hoba meteorite, resulting in a unique crystalline Widmanstätten pattern for every individual timepiece. The dial features high-contrast black sub-dials and is protected by a black monobloc Cerachrom ceramic bezel with an engraved tachymetric scale for measuring average speeds. It is fitted with a black Oysterflex bracelet, which combines the robustness of a metal blade with the comfort of a high-performance elastomer, and is secured by an Everose gold Oysterlock safety clasp with the Easylink comfort extension system.
Internally, the watch is powered by the Rolex Calibre 4130, an in-house self-winding mechanical chronograph movement that is COSC-certified and features a vertical clutch for smooth engagement. The movement provides a 72-hour power reserve and utilizes a Parachrom hairspring for enhanced resistance to shocks and magnetic fields. In terms of complications, the watch includes a central chronograph seconds hand capable of 1/8 of a second precision, along with a 30-minute counter at 3 o’clock, a 12-hour counter at 9 o’clock, and continuous small seconds at 6 o’clock. The Oyster case employs a Triplock triple waterproofness system and screw-down pushers to ensure water resistance up to 100 meters.
General reviews of the 116515LN-0055 emphasize its exceptional aesthetic appeal and the exclusivity provided by the meteorite dial, which collectors often view as a grail-level feature. Experts frequently praise the balance between the warmth of the Everose gold and the technical, sporty look of the Oysterflex strap. While the watch is celebrated for its legendary movement and perfect proportions, some reviewers note that the meteorite variants are produced in extremely limited quantities, making them significantly harder to obtain at retail than standard models. Additionally, while the Oysterflex is highly regarded for its comfort, a common minor criticism among traditionalists is that the watch cannot be easily swapped for a full gold bracelet due to its specific lug design.
