The Montblanc Heritage Pythagore Small Second Limited Edition 148 marks the debut of the new MB M14.08 manufacture movement inspired by the historic calibre 48 of the Minerva Pythagore from the 1940s. The bridges of this calibre were positioned according to the golden ratio, which resulted in harmonious and pleasing aesthetics. The straight lines and geometric angles in particular were exceptional. Montblanc made use of this very same architecture when designing the new MB M14.08 calibre.
