Up Close Look at the New Rolex Caliber 3255
Take a look at what is being called the new-generation Rolex movement with the new Rolex Caliber 3255. The noteworthy new item sets a new level of chronometric precision with criteria surpassing those of the Swiss Official Chronometer Testing Institute. In fact, Rolex has developed a new methodology and high-technology equipment to test the precision of its Superlative Chronometers with tolerances that are twice as precise as the ones used for official certification.
These exclusive tests complement the official COSC certification, to which all Rolex movements continue to be submitted systematically, and are carried out not on the movements alone, but on the assembled watches after the movements.
If you take an up close look at the 3255, you’ll see how it incorporates the new Chronergy escapement patented by Rolex, which combines high energy efficiency with great dependability. You’ll see that the oscillator has an optimized blue Parachrom hairspring, which is up to ten times more precise than a traditional hairspring, and a ton of other great new features as well!
