Demonstrating the brand's forward-thinking approach to traditional design, it eschews the vogue for tone-on-tone dials to improve readability of the markers. The face also reveals the exceptional mechanism beneath, still the only series-made chronograph in the world capable of measuring short times to the nearest tenth of a second. The black alligator strap gives this heirloom timepiece a luxurious edge. We offer a two-year warranty for all working parts and manufacturing faults for luxury watches.
