The new William Baume Collection is a tribute to time and its measurement. Through a splendid array of haute horlogerie models, it evokes the noble traditions of one of the oldest Swiss watch brands, Baume & Mercier. This time-honored expertise is admirably embodied by the figure of William Baume, the man who forged the company's contemporary destiny and was instrumental in earning it the prestigious Poinçon de Genève in 1921, the seal acknowledged as the highest watchmaking quality certification.
Jumping Hour is a complication that displays the hours in the form of numbers appearing through an aperture, instead of showing them with a hand. Jumping Hour models are thus referred to as the first “digital” watches in horological history. Printed on a rotating disk, the numbers instantly “jump” when the hour changes, while the minutes and seconds are generally indicated by hands.
Newly launched in 2010, this interpretation of the William Baume Collection displays the hours in an aperture at 12 o'clock, while the minutes and seconds are indicated by Rose Gold hands on two separate sub dials. The black dial is adorned with a cross weave guilloché motif and sunburst satin-brushed finish on the sub dials. The self-winding movement is visible through the large opening in the sapphire crystal case-back, enabling one to admire the circular-grained and snailed finishing on the mainplate and bridges, as well as the openworked oscillating weight with Côtes de Genève decoration.
The XL sized (41 mm) case is crafted in 18-carat Rose Gold with applied lugs. The hand-sewn black alligator leather strap is enhanced by a Rose Gold pin buckle. This new William Baume model was launched in a limited numbered series of 40, This watch is numbered 26 out of 40.
