The Rolex Daytona, a watch synonymous with motorsport, luxury, and enduring style, has a history as compelling as its design. The watch's journey, particularly the period surrounding the shift from Zenith-produced movements to in-house calibres, is a fascinating case study in horological engineering, strategic partnerships, and the relentless pursuit of perfection. This article will delve into the intricacies of the movements powering the Daytona, addressing the reasons behind the extended development period for the in-house calibre, and exploring various aspects of this iconic timepiece.
What is Rolex Daytona? (Krg?)
The Rolex Cosmograph Daytona is a chronograph wristwatch, renowned for its precision, durability, and prestigious status. The "Krg" designation, if encountered, is likely a reference to specific retailer or internal Rolex coding and doesn't denote a distinct model variation. The Daytona's fundamental design remains consistent throughout its evolution, featuring a tachymeter bezel for speed calculations, three chronograph sub-dials (for seconds, minutes, and hours), and a robust Oyster case. The watch has become a highly sought-after collector's item, with certain models fetching astronomical prices at auction.
Rolex Daytona with Zenith Movement:
For a significant portion of its history, the Rolex Daytona relied on movements supplied by Zenith, a renowned Swiss watch manufacturer. Specifically, the El Primero calibre, a high-frequency automatic chronograph movement, powered several Daytona references, notably the 16520. This collaboration, beginning in the 1980s, marked a significant period in the Daytona's development. The El Primero, with its impressive 36,000 vibrations per hour (vph), provided the Daytona with the accuracy and reliability expected of a professional chronograph. The combination of Rolex's design expertise and Zenith's advanced movement technology resulted in a highly successful and popular watch.
The use of the Zenith El Primero movement in the Rolex Daytona is a testament to the recognition of external expertise. Rolex, despite its in-house manufacturing capabilities, recognized the superior performance of the El Primero, a decision that highlights the company's pragmatism and commitment to delivering the best possible product. The collaboration, however, was not without its complexities. The partnership eventually dissolved, paving the way for Rolex's ambitious goal of producing an in-house movement for the Daytona.
Explain the Rolex Daytona's Operations:
The Rolex Daytona's operation is relatively straightforward, despite the complexity of its movement. The watch features:
* Timekeeping: The main timekeeping function is displayed on the central hour and minute hands, with the seconds hand located at the subdial at the 6 o'clock position.
* Chronograph Function: The chronograph function allows the user to time elapsed intervals. The chronograph is activated by pressing the pushers located at 2 and 4 o'clock. The seconds hand starts recording elapsed time, while the 30-minute counter (at 3 o'clock) and the 12-hour counter (at 9 o'clock) record longer durations. Resetting the chronograph is achieved by pressing the pusher at 4 o'clock.
