Rolex describes the Daytona as follows: The Cosmograph Daytona, introduced in 1963, was designed to meet the demands of professional racing drivers. With its highly reliable chronograph and bezel with tachymetric scale, it allows drivers to perfectly measure average speeds up to 400 kilometers or miles per hour, as they choose. An icon eternally joined in name and function to the high‑performance world of motor sport. Now I will expand on this with a brief description of the Daytona at hand. Quite possibly the most impressive luxury sport watch you may ever encounter, this particular Daytona has a 40mm case made of 18kt yellow gold. The black Rubber B strap with Rolex deployant buckle helps to ground the watch, making it suitable for everyday wear.This watch is powered by calibre 4130, a self-winding mechanical chronograph movement entirely developed and manufactured by Rolex. The black dial with yellow accents reminds one of the classic John Player Special models. In keeping the size to a subtle 40mm, Rolex has knowingly chosen style over substance, creating the perfect blend of classic design and modern materials. This watch does not come with box or papers.
