Montblanc TimeWalker Pythagore Ultra-Light Concept Watch

Dedicated to World Badminton Champion Lin Dan, the Montblanc TimeWalker Pythagore Ultra-Light Concept Watch is an intriguing mix of modern engineering and old-world technique. The 40mm case is made using black DLC titanium for the lugs and ITR2, a composite material made from carbon nanotubes, mixed with Kevlar carbon for the middle case, back, bezel, and crown. The dial is skeletonized and the case back made from mineral glass, letting you get a good view of the Calibre MB M62.48 movement that's based on Pythagoras's Golden Ratio and recalls the Minerva Pythagore movement from 1943. The end result is one of the world's lightest mechanical timepieces — it weighs just 14.88 grams — and when paired with the black nylon strap, one of its more striking, too. (uncrate)
