This Rolex Cosmograph Daytona, reference 6263, is a manual-wind chronograph featuring a 37mm steel Oyster case with screw-down pushers and a black bakelite tachymeter bezel.

The watch is powered by a Valjoux 727-based movement. It is identified by its silver soleil dial with a floating “Big Red” Daytona signature positioned above the 6 o'clock register. The dial includes three sub-registers, which the auction description reports have developed a subtle brown discolouration. The luminous plots are described as aged to a vanilla tone, and the hour and minute hands have been replaced during a recent service.

The watch is presented on a Rolex 78350 Oyster bracelet with 557B endlinks and an M4 clasp code. According to the provided specifications, the serial number 641xxxx dates the watch to 1980.

Design

Dial and Hands
The silver soleil dial features a floating “Big Red” designation, where the word “DAYTONA” is curved above the 6 o'clock register. The sub-registers are described as having acquired a subtle brown discolouration, contributing to the watch's appearance. The luminous plots are noted to be intact with a warm vanilla age tone. While the dial is described as mark-free, the auction description reports that the hand-set is not original to the watch, having been replaced during a service.

• Floating 'Big Red' text above sub-dial • Black bakelite bezel • Screw-down pushers • Silver soleil finish on dial
Movement and Bracelet
Internally, the timepiece is equipped with a Valjoux 727-based mechanical movement. The auction description reports that the movement has undergone a recent service performed by the vendor's watchmaker. The watch is secured to the wrist by a Rolex 78350 Oyster bracelet. This bracelet is specified as having 557B endlinks and an M4 clasp code.
Case and Bezel Construction
The watch is housed in a 37mm steel Oyster case, a design choice which incorporated screw-down pushers to improve water resistance. This reference is distinguished from earlier models by the presence of these pushers and the fixed black bakelite tachymeter bezel. The auction description reports that the Mk4 bakelite bezel is free from cracks or blemishes. The stainless steel case is described as having a well-preserved profile with sharp and even lugs.
