A Stainless Steel Automatic Sweep Seconds Wristwatch with Date, 24 Hours and Bracelet, Rolex, Oyster Perpetual, 'GMT-Master', Ref. 1675, Circa 1963

nickel lever movement, 26 jewels, monometallic compensation balance, adjusted to 5 positions and temperature, black matte dial, luminescent triangular, dot and baton indexes, magnified aperture for date, rotating bezel calibrated for 24 hours divided into diurnal (red) and nocturnal (blue) hours with small triangular indicator hand, tonneau water-resistant-type case with screw back and screw-down crown, case, dial and movement signed, with stainless steel Rolex Jubilee bracelet and deployant clasp.

As the gilt lettering and tracking on GMT-Masters, such as the present lot, was discontinued by the end of the 1960s, there are fewer examples with such dial features. Such models are therefore more desirable on the market today.
