勞力士，精細及罕有，14K金計時碼錶，"Daytona"，型號6241，約1969年製

Reference 6241 was introduced into the market in the early 1960s and remained in production until around 1969. Available in stainless steel, 14K and 18K gold, it was fitted with the "non-Oyster" or "non-screw down" chronograph buttons and a bezel with black plastic insert, the tachymetre scale printed in white. Models in 14K gold, such as the present watch, were exclusively reserved for the North American market. The dials featured the designations "Rolex Cosmograph" but not always the "Daytona".
