A mid series Rolex Cosmograph Reference 6265 on offer here - with the serial dating the watch to 1976

With a practically flawless dial (I say practically as there is some surface dust, however no marks visible whatsoever) and a thick case this is a sublime example

Note the super fat and puffy tritium lume (slight loss at 3, a common story and a reassuringly tell tale sign of originality as this is always the first of the plots to "go over time") - matches the hands perfectly and fall off quickly under UV as it should - the pumpkin hue really gives this example a little something special

Add to the wide and unmolested steel bezel, the overall aesthetic is one of superlative homogeneity 

Fitted to a C&I stretch rivet bracelet dated 78

Service history unknown but running strong and with high amplitude and an immaculately well maintained movement
