It is difficult to say which Rolex model is the best, because individual tastes can't be defined with as much accuracy and precision as these Swiss watches.

From a purely personal point of view, I think the DateJust collection offers the most versatility, at least as far as the combination of classic elegance and functionality is concerned. Historically, too, the DateJust was a milestone setter for Rolex, as it was the first watch to feature the date display through a clearly visible magnifying Cyclops lens.

Launched in 1945, the DateJust was the culmination of all Rolex's virtues: chronometer-certified, water-resistant (up to 330 feet / 100 metres), with an automatic winding. And, of course, the most important feature in a watch - punctuality. The "just" in the name stands for "just in time" because the date display advances to show the next day's date at precisely midnight.

While the DateJust's basic design did not dramatically change since its inception, some aesthetic touches have been added over the years, such as Rolesor, for example.

For those who don't know, Rolesor is Rolex's term for the combination of stainless steel with the yellow, white or pink 18-carat gold, a look that jazzes up either all-steel or all-gold models. It derives from the terms Rolex (naturally), and Or, the French word for gold.

Many of the DateJust Rolesor models also boast refined details, such as smooth and domed bezels in addition to the traditional fluted ones, as well as better visibility thanks to larger dials and hands. Also, the gold central link of the Oyster bracelet is offset by narrower links of solid steel for a snugger fit.

If you like functional, sturdy and no-frill watches that will withstand a lot of wear and tear, a sports model like the Explorer might be a better choice than the DateJust.

But for those who like dressy elegance and the two-tone combination of Rolesor, this DateJust model is, wrists down, a great choice.

DateJust has been a timeless classic since its introduction, and celebrities took to immediately. Still favoured in recent decades, Kurt Russell was seen wearing one in "Tequila Sunrise," (1988, if you didn't remember) and Matt Dillon even resorts to stealing a Rolesor watch in "One Night at McCool's" (although the real prize he was after was the DVD player...)

Recently, Rolex caused a bit of a stir with some flashy adverts of DateJust models in Rolesor, adorning the wrists of attractive, fun-loving younger people "out on the town". Although an instantly recognisable brand the world over, Rolex's long history demands that the brand's image take an occasional dip in the Fountain of Youth.

Some adverts from the Far East don't reach us in the West, although they'd certainly have an audience here as well. Below, Brad Pitt (an American) models Rolex watches (Swiss) for an advertising campaign in Japan. Brilliant.
