C'est une analyse technique, horlogère... en anglais... Il y a de nombreuses photos du calibre démonté...

Un tout petit extrait de sa "conclusion" :

...

As for me, please keep in mind that no movement is perfect and that they all have their strengths and weaknesses. Having said that though there is absolutely no question in my mind, that I prefer the ETA 2892-2A over the other two. Okay, so it’s been around almost half a century and in many ways isn’t as sophisticated as the Rolex – no Breguet hairspring, or Parachrom hairspring material etc – but during its long lifetime in its best available chronometer version, it has proven itself to be an exceptionally accurate, reliable and tough movement. Its two main advantages over the 3135 are that it’s quite a bit thinner, only 3.6mm thick versus 6mm, and has only one major weakness – the inefficiency of its automatic winding system, as I mentioned in my earlier review of it. While good enough for most reasonably active folk, it is not efficient enough for those people, young or old, who lead a sedentary lifestyle.
