With the Endeavour Perpetual Calendar Black Edition, H. Moser & Cie. ventures into new territory. The Manufacture explored high-tech materials to complement its collection in gold and platinum, in search of the perfect functional material to accompany its pure design. Titanium was chosen for its exceptional mechanical properties. It is very hard, easy to wear, hypoallergenic and extremely light. It also brings a unique urban yet timeless black finish to the watch that puts a focus on form and perfect surfaces.
