Rolex Updates the Classic Datejust
The Replica Rolex Datejust is perhaps the quintessential wear-it-anywhere-suit-or-jeans Replica Watches. On the 60th anniversary of the original launch, Replica Rolex presents the Oyster Perpetual Datejust II Rolesor. The new model updates the classic Datejust design with a 41mm case. Available in steel and either white or yellow gold with a fluted bezel, the Datejust II is waterproof to 100 meters. The COSC-certified movement is designed and manufactured in house and it features a Parachrom hairspring and Paraflex shock absorbers. The steel and gold Oyster bracelet is fitted with an Easylink extension link for added wearing comfort.
In days gone by, when ships relied on marine chronometers to navigate, timekeeping accuracy was a paramount concern not only to sailors, but to entire nations. Manufacturers sent their finest handmade and hand-adjusted marine chronometers to be tested at astronomical observatories, such as those at Neuchâtel, Geneva, Besançon and Kew. Each observatory applied its own standards, and Kew reportedly applied the strictest of all. The tests were far more demanding than those employed by COSC today. For decades, only hand-adjusted marine chronometers with detent, or chronometer, escapements passed the tests. At Kew, chronometers that performed especially well received an A-class certificate.
In 1914, a Replica Rolex wristwatch received the first-ever Kew A certificate for a timepiece of that type. During the 1940s, Rolex submitted a series of 145 small wristwatch movements to Kew for testing. To the amazement of practically everyone (except perhaps Hans Wilsdorf and his staff), 136 of the movements received Kew A certificates. The movements Rolex submitted were among the least expensive it produced – 10 ½ “’ Hunters, though each was fitted with standard production balance wheels and escapements intended for another movement, making the “Kew A” movements a sort of hybrid. These movements were specially hand finished, and each was adjusted by Replica Rolex’s master timer, Jean Matile. Most of the movements were used in steel, 32 mm Oyster Speedking watches, while 24 of the movements were placed in 34 mm gold cases and sold as model 6210. Needless to say, today these watches are among the most sought-after by collectors.
