Omega's new Speedmaster isn't a total overhaul, its merely a refined variation of an already perfect watch. Speedmaster fans will notice the change of the usual three subdials to two. Omega elegantly consolidated the 12 hour and 60 minute counter at 3 O'Clock for easier chronograph reading. The watch also takes advantage of the company's new 9300/9301 movement which combines their Co-Axial calibre with a chronograph function. Link
