This genuine Rolex Daytona is in excellent condition for a vintage timepiece of it's age. The watch shows minimal case wear consistent with its age. Rolex Serial No. 1 * * * * * 8 denotes 1964 production year. The watch is sold "as is" and "as photographed", this watch does not come with the original box or papers. Watch movement is functioning as normal. *Following the production of the Reference 6238 'Pre-Daytona' chronographs, Rolex introduced the first to models to bear "Daytona" nomenclature on their dials - the model offered here, a Reference 6239. Introduced in 1963, these pieces were also the first to feature a tachymeter bezel and a contrasting dial and sub register layout that has become a coveted characteristic of Daytonas. This particular Reference 6239 is an early example dating to circa 1964 and features a lovely reverse panda Tritium dial, a domed acrylic crystal, steel tachymeter bezel, signed crown, pumper-pushers and a later solid-link Jubilee bracelet with a signed blade clasp. The venerable Valjoux 72 manual movement provides power, as it did for its immediate predecessor and every other Daytona model - including the legendary 'Paul Newman Daytona' until the introduction of the Reference 16520 in 1989.
