Here at analog/shift, we have a passion for timepieces with tradition, style and value. When these elements combine, an icon is formed,and it is hard to get more iconic than the brand with the big crown - Rolex.

When you think of Rolex, your first thoughts may be to its unforgettable GMT Master with its two-tone "Pepsi" bezel, the aviator's timepiece designed with Pan-Am pilots and transatlantic jet flights in mind. Or it might go to the form-follows-function Explorer I, the watch designed for mountaineers and tested under the most extreme conditions on earth. But it probably goes to the Submariner, the legendary diver by which all others are measured.

There's no denying that a Rolex Submariner is one of the most iconic watches of the last 60 years, but the same can easily be said about its sibling, the Datejust. Designed for the fluctuating conditions faced in everyday wear, the Datejust was the world's first wristwatch ever to incorporate a date function, and has been worn proudly by , athletes and movie stars - and probably your grandfather. We’ve said it before and we’ll say it again; with perfect portions, a robust automatic movement and timeless styling, the Rolex Datejust may simply be the most versatile and wearable watch ever designed.

This particular Datejust (Reference 1603) dates from approximately 1973 and features a classic 36mm Oyster case, crisp machine-turned steel bezel, and flawless and rare matte black dial. This is a simply stunning vintage piece, and paired with nylon or leather strap or the included solid link Jubilee bracelet, is arguably the only watch a modern gentleman would ever need.
