Here it is folks, the most anticipated watch on the planet - the MB&F HM4. Now writing our 5th post about this watch, we have to say that few designs would be capable of not only living up to the hype that Porsche Design Sportivo Chronograph PDSC320 watches surrounds around this concept, but actually surpassing all expectations of what this new creation could be.The watch consists of two dials that sit side-by-side. One displays the hours and minutes (read as a plane's speedometer), and the other displays the engine's power reserve (aka the plane's fuel levels). Both dials are displayed at the end of a turbine like pod, opposite individual crowns. This means one crown is for setting the time, the other is for winding the engine.There are five unique pieces of sapphire glass on the HM4, and the main Porsche Design Sportivo Chronograph PDSC320 watches sapphire plate actually costs more than the entire engine of the HM2. Think about that. The engine itself is a marvel, taking over 3 years to develop, consisting of 311 parts, and converting power from a horizontal dual mainspring barrel to two vertically oriented gear trains to display on the dials. No easy feat.
