Rolex DatejustAfter World-war 2 Rolex created the first self-winding waterproof chronometer wristwatch that featured a date indication. For the first 10 years of production the date, shown at the 3 o’clock position, was not yet enhanced by the well-known ‘Cyclop lens’. This lens was introduced in 1955 and magnified the date by 2.5 times. The Cyclop lens isn’t the only invention, that we can still see up to today, the Datejust set in motion. The Jubilee bracelet was designed especially for the Datejust. The iconic elegance of this 5 piece bracelet is a great match to –arguably- one of the best buys in the vintage watch market.OvettoneThe nickname 'Ovettone' is Italian for big egg and covers a couple of early Datejust reference numbers that have a certain kind of case back. This protruded 'bubble back' was designed to house the newly introduced date wheel to the movement. The production started in 1945 and these early Datejusts are loved among distinguished Rolex collectors that want a truly special piece within one of the most common Rolex lines.
