I’m positive that you all know MB&F’s Horological Machines. It started with number 1 (of course) and the latest Horological Machine is HM5 , which was introduced in December of last year. This also means it’s time to say goodbye to HM4 and that happens with HM4 Final Edition.
Horological Machine 4, which was introduced in 2010, is my favorite Horological Machine and the black piece unique made for Marcus Watch in London was probably my favorite HM4. Its black color made it even more daring and stealthy. For the HM4 Final Edition, there are just 8 pieces, Max Busser found his inspiration in the F-117Nighthawk Stealth. Read on to find out why.
