Start, drive, break records. One press to start the chronograph. Time intervals can be measured to within one-eighth of a second with the arrow-tipped centre hand, while the two counters on the dial at 3 and 9 o’clock display elapsed time in minutes and hours respectively. Racing drivers can accurately map out their track times and tactics without fail. #Rolex #CosmographDaytona #Perpetual #HLBrown #Sheffield #OfficialRolexRetailer
