I've been following 4N ever since I set at the bar in Palace (one of the Baselworld locations) and met with Mr. Francois Quentin. We drank a cup of coffee and he told me about his new creation and showed me some drawings. Can't remember if he also showed me a prototype, but I believe not. In 2010 he showcased his 4N prototype in Hall 4.1 at Baselworld.
Today I found a video uploaded by HauteHorology on YouTube and thought to share it with you all. Hope you'll enjoy watching it:
