Today, each and every watch in Rolex’s list contains a chronometer-ensured, in-house development. Indeed, even current Cellini watches are guaranteed chronometers; anyway their dials do exclude the accompanying, “Standout Chronometer Officially Certified” text that shows up on the remainder of the other Rolex watches.
The Rolex Cellini line of watches are affirmed chronometers, yet they don’t have it composed on the dial like other Rolex models
In expansion to the business standard, COSC testing, Rolex observes additionally go through Rolex’s own and more tough, “Standout Chronometer” testing, which ensures timekeeping to +/ – 2 seconds out of each day, in the wake of packaging. In spite of the new move towards the far reaching utilization of chronometer guaranteed developments and extra, more severe certificates, the absolute generally esteemed and longest running references from Rolex’s set of experiences didn’t contain chronometer ensured movements.
Many of the Rolex’s initial games watches, which are presently viewed as ultra uncommon and collectable today, were not guaranteed chronometers, including most vintage Daytona chronographs and by far most of right on time, pre-crown-monitor Submariners. Notwithstanding, a couple Rolex watches, most strikingly the no-date Submariner and the Air-King clutched their non-COSC guaranteed developments well into the advanced era.
The Submariner 5513 is quite possibly the main jump observes ever, and was a non-chronometer watch
The reference 5513 Submariner was presented in 1962 as a more moderate option in contrast to the chronometer-confirmed, reference 5512. Albeit the two watches were practically indistinguishable on their outsides, the reference 5513 depended on Rolex’s type 1520, which was not COSC-evaluated. Because of its more spending plan well disposed development, the reference 5513 did not have the extra “Standout Chronometer Officially Certified” text on its dial.
Production of the reference 5513 went on until 1989, when Rolex at last supplanted it with the reference 14060; nonetheless, even the updated form of the no-date Submariner didn’t get a chronometer-guaranteed development. Indeed, the no-date Submariner was just accessible as a non-COSC evaluated watch from the time that Rolex stopped the reference 5512, right until late 2007, when the reference 14060M was at long last given a similar chronometer-appraised status of its date-showing sibling.
While the “Standout Chronometer Officially Certified” text on the dial of Rolex watches is planned to be a sign of accuracy and accordingly saw as a symbol of honor, numerous authorities lean toward the style of the less content hefty, “2-line” dial on the no-date Submariner because of its expanded negative space and rearranged design.
The Rolex Air-King 5500 was made to be a moderate non-chronometer watch, similar to the 5513 Submariner
Much like the reference 5513 Submariner, the Air-King was initially made to be a dependable, nitty gritty watch that could involve a section level spot in Rolex’s arrangement. The reference 5500 was presented in 1957, and remained to a great extent unaltered for the total of its long term creation run. Like the reference 5513 Submariner, the reference 5500 Air-King had the option to accomplish its lower value point by utilizing the equivalent, non-chronometer evaluated, type 1520 development as the reference 5513 (albeit some Air-King watches were fitted with the type 1530).
Consequently, reference 5500 Air-King watches don’t have the words, “Standout Chronometer Officially Certified” imprinted on them; anyway some are marked with “Accuracy” or “Super Precision” all things considered. The diminished measure of text improves on the dial and adds negative space; anyway some early creation run, reference 5500 watches have positively no content imprinted on the lower half of their dials. These “pre-accuracy” dials are the absolute generally perfect and basic dial plans that Rolex has at any point advanced, and are symbolic of a prior and less normalized time in Rolex’s history.
It wasn’t until a lot later that the Air-King was COSC rated
Much like the no-date Submariner, the Air-King didn’t get a chronometer-confirmed development when Rolex delivered an ensuing age of Air-King watches. It was not until 2007, with the presentation of the reference 1142xx arrangement, that the Air-King at long last turned into a guaranteed chronometer and had the accompanying, “Standout Chronometer Officially Certified” text added to its dial.
Many of Rolex’s initial watches are not ensured chronometers; be that as it may, a moderately modest number of non-chronometer watches figured out how to stay underway for various a long time while never accepting a COSC-evaluated development. Albeit non-chronometer confirmed watches don’t guarantee an incredible same level of timekeeping as their COSC-appraised partners , they regularly possess the absolute generally perfect and basic dials fitted to any Rolex timepieces.
