Rolex Cosmograph Daytona 126500ln-0001 In-Depth Review: Precision and Performance in a Timeless Design

Rolex designs the Oyster Perpetual Cosmograph Daytona 126500ln-0001 in Oystersteel, pairing a white dial with bold black counter rings. This model comes with an Oyster bracelet and a black Cerachrom bezel engraved with a tachymetric scale, blending cutting-edge technology with a design inspired by the classic 1965 Daytona.

The tachymetric bezel enables drivers to measure average speeds up to 400 miles or kilometres per hour. Rolex uses high-tech ceramic for the monobloc Cerachrom bezel, which resists corrosion, remains virtually scratchproof, and keeps its colour under UV exposure. To improve legibility, Rolex applies platinum into the numerals and graduations using a Physical Vapour Deposition (PVD) process. This single-piece ceramic bezel adds durability and securely holds the crystal to ensure waterproofness.

The Daytona's white dial with snailed counters includes 18 ct gold applique hour markers and Chromalight-filled hands emitting a highly visible luminescence. This layout gives drivers precision in timing and clear visibility for race tactics.

Rolex forges the Cosmograph Daytona case from Oystersteel, an alloy it developed for maximum corrosion resistance. As part of the 904L steel family, Oystersteel withstands extreme conditions while maintaining a lasting polish and shine, which is ideal for this rugged model.

The Daytona's robust Oyster bracelet, introduced in the 1930s, combines comfort with strength through its flat, three-piece links. Rolex rigorously tests each bracelet and clasp, combining advanced technology with human inspection to ensure an impeccable finish and reliable functionality.

The Daytona includes a centre chronograph seconds hand and 30-minute and 12-hour counters for accurate timekeeping for speed enthusiasts. Rolex incorporates Chromalight elements into the dial, enhancing readability with luminescent material.

The 40 mm Oyster case, waterproof up to 100 metres (330 feet), demonstrates Rolex's engineering excellence. It features a Triplock winding crown with a triple waterproof system and a crown guard as part of the case. The screw-down crown and chronograph pushers ensure added protection. The scratch-resistant sapphire crystal has an anti-reflective coating, keeping the display clear under any condition.

Finally, Rolex powers the Cosmograph Daytona with a self-winding mechanical movement entirely crafted in-house. With this level of precision and resilience, the Daytona is a perfect choice for those who value performance and speed.

• The Striking White Dial
• The Black Cerachrom Tachymetre Bezel
• The Rolex Calibre 4131

The Striking White Dial

Rolex equips the Oyster Perpetual Cosmograph Daytona 126500ln-0001 with a striking white dial featuring snailed chronograph counters. It places 18 ct gold applique hour markers and hands on the dial, filled with Chromalight, a luminescent material for superior legibility. The hour markers with Chromalight ensure drivers can read the time accurately, even in low-light conditions, while tracking lap times and race tactics. The carefully crafted layout combines functionality with aesthetic appeal, making it a perfect tool for precision timing on and off the track.

The Black Cerachrom Tachymetre Bezel

The bezel of the Rolex Oyster Perpetual Cosmograph Daytona 126500ln-0001 stands out for its black Cerachrom construction, which offers exceptional durability. The bezel, made from high-tech ceramic, is resistant to corrosion, virtually scratchproof, and unaffected by UV rays, maintaining its colour over time. It features a tachymetric scale, allowing drivers to measure average speeds up to 400 miles or kilometres per hour. Rolex enhances the legibility of the scale by applying a thin layer of platinum to the numerals and graduations through a PVD process. The monobloc bezel, made in a single piece, also ensures the crystal remains securely in place, contributing to the watch's waterproof design.

The Rolex Calibre 4131

The Rolex Cosmograph Daytona 126500ln-0001 equipped the watch with the Rolex Calibre 4131, an automatic movement offering a power reserve of approximately 72 hours.

Rolex develops the Calibre 4131 as a self-winding chronograph movement, building on the technological advancements of its predecessor, the Rolex Calibre 4130, while incorporating significant improvements. This high-performance movement includes two patented mechanisms: Paraflex shock absorbers, which protect the oscillator from impact, and the Chronergy escapement, which resists high magnetic fields and reduces energy loss. The self-winding mechanism benefits from an optimised ball bearing in the Perpetual rotor, increasing durability. Rolex gives the movement a fresh look with bridges featuring the exclusive Rolex Côtes de Genève decoration. The Rolex Calibre 4131 introduces innovative and patented technical solutions, setting a new standard for robustness, reliability, efficiency, and precision.

Rolex also adapts Calibre 4131 for special editions of the Cosmograph Daytona, created in honour of the 24 Hours of Le Mans endurance motor race. This version, Calibre 4132, includes a patented mechanism that allows the chronograph to measure 24 hours instead of the usual 12.
