If it’s a stylish yet sporty watch she’s after the Rolex Datejust 31mm is my candidate of choice - the kind of watch that can be worn day in day out and look great in every situation. The rich chocolate-brown dial features Everose gold Roman numerals, the Rolex crown at 12 o’clock and the date window with a Cyclops lens at 3 o’clock. For an extra dash of femininity, the numeral VI is enlarged and sparkles with diamonds, as is the domed Everose gold bezel, which is set with two different sizes of diamonds. As a descendant of the legendary Oyster watch of 1926, this model is water-resistant to 100 metres and equipped with a mechanical automatic movement with a precision rating exceeding that of almost any other watch on the market today. The strap of this Datejust 31mm model is a classic Rolesor bracelet combining the warmth of Rolex’s proprietary Everose gold with the practicality of stainless steel.
