Since it has been brought into being in the Swiss Jura Mountains in 1830, the watchmaking house Baume & Mercier followed just one single vision: ‘Accept only perfection!’. That being said, it’s self-evident, that a limited masterpiece such as this Monopusher Chronograph, receives comparatively more attention and devotion as their crafts in series already receive. This precious limited edition comprises just 20 pieces in a 41mm 18kt gold case, each individually numbered on the back with an additional William Baume Collection lettering. The face characteristics are explained by classic Roman numerals, a line guilloché décor, and a Baume & Mercier emblem, which carefully signifies the masterful craftsmanship, that shows its quite perfection on the open case back when admiring the 21 jewels of the manual-wind Lajoux-Perret caliber 5000 through a flawless sapphire crystal display.
