it starts as a Top grade ETA 2824-2, modified to have KIF shock absorption, and a Triovis fine-adjustment regulator.
Decoration is one thing, but many companies have decoration applied to the higher end 2824-2's for use in chronometer grade watches - Brietling for example.
The Tudor 2824-2's start as Top grade, so they have all the parts that the Chronometer grade movements do, without the actual testing being done. The shock system is then changed from Incabloc to Kif, and they remove the ETACHRON system, and implement a more traditional stud on the balance spring, and traditional regulator pins.
For me as a watchmaker who services these movements, removing the ETACHRON is not an advancement, but a step backwards. Adjusting the centering of the balance spring, the centering of the outer coil through the regulating pins, and setting the spacing of the regulating pins is so much easier with the ETACHRON system, it really makes no technical sense (in my opinion) to remove this system. There's no doubt that a watch can be adjusted just as well using the traditional systems, but is it far less time consuming with the ETACHRON system. I suspect the Rolex does this because they want to make it their own, and not for any technical reason.
Hope this helps.
