When the first Rolex Datejust was introduced in 1945 - the year of the brand's 40th anniversary, it made history as the first automatic water-resistant certified chronometer with a date on the dial. The 'Cyclops' was added in 1955 to magnify the date display by two and a half times, thus making the reading more legible and clear, and this feature became one of the most recognizable Rolex hallmarks of all. In 2009, Rolex introduced the Rolex Datejust 36. This line of timepieces offers the features of the original and iconic Rolex Datejust in a simpler and more modern design and includes new innovations. One of the most significant differences between the previous version and the new one is of course the movement - the Datejust 36 has the honor of carrying within it, made by the brand exclusively for this model, the caliber 3135 - an in-house movement with Paraflex anti-shock protection, a Parachrom hairspring, a COSC certified chronometer with a 48-hour power reserve, operating at 28,800 vibrations per hour. It is not for nothing that the Datejust is the brand's most popular and recognizable model after the iconic Submariner – and the Datejust 36 allows this popularity to be presented in a contemporary interpretation. This particular watch is one of the brand's models whose combination of a fluted bezel, Oyster bracelet, and a blue dial with white gold Roman numerals makes it very rare and sought after by the brand's admirers. Indeed, the detail of this timepiece (as with all the modern Rolexes we have had the opportunity to examine) is impressive. Starting with the incredible dial (in this case, in a classic blue color, which Rolex calls Blue Roman), which at certain angles gives the impression that the hands and markers are 'suspended' in the air in a state of weightlessness. Moving on to the classic sapphire with the 'cyclops' – in this case, the brand's highest grade of sapphire is used, which has allowed the overall height of the watch to be reduced compared to its predecessors. Of course, separate attention must be paid to the case and the bezel – an incredible combination of brushed highest-grade 904L steel with faceted polished edges and details in places (as you know, Rolex pays special attention to the steel used and for this purpose has its own foundries for the production of all its alloys) and a classic 18-karat white gold bezel, which gives an incredible radiance and has a great presence on your wrist. And of course the bracelet, or whatever you may call it – as can be expected from a Rolex, it is truly good... In this case, it is the new Oyster bracelet with a solid clasp, crafted from a single block of steel (and not from bent sheet metal, as is the case with most brands) – the only thing it lacks (but perhaps only in my opinion) is the Sub's GlideLock clasp, but here the so-called EasyLink is fitted, which allows for micro-adjustment with an additional 5 - 20mm at the lugs.
