Additional Informations: This Rolex Daytona reference 6263 dates from 1974 and brings together a number of compelling characteristics that make it unquestionably collectible. If we had to describe its condition in one word: exceptional.
It begins with the beautifully preserved black Sigma dial – deep black with fully intact luminous plots and a clean, well-balanced typographic layout. Complementing it is the original T21 domed plexiglass, which accentuates the classic silhouette of this reference. The watch is framed by a near-pristine MK2 black bakelite bezel, with sharp, crisp markings – a rarity for such a fragile material.
The 7835 Oyster folded-link bracelet with 271 endlinks and the rare "B" clasp code suggests the watch was likely sold around 1976.
The winding action is notably smooth, the movement runs precisely, and all chronograph registers function as intended.
Special attention must be given to the case: it was not simply “polished,” as the term is often misused, but carefully and deliberately restored by Bob Kolican - one of the most respected names in high-end vintage case refinishing. His work is considered a benchmark in the field, known for retaining original geometry, sharp lines, and balanced finishing. This watch has not been given a superficial shine - it presents as if it had just left the display tray decades ago.
This is a rare opportunity to acquire a Rolex Daytona 6263 that stands out for its overall coherence, mechanical integrity, and expertly finished case - a thoughtfully assembled collector’s piece in a configuration that seldom surfaces on the market.
