In shades of anthracite and blue, this Endeavour Perpetual Calendar revisits H. Moser & Cie.’s emblematic complication in a visually striking manner. Combining tantalum, a stable and durable metal with a unique hue that’s exceedingly difficult to machine and polish with the ancestral technique of “grand feu” enamelling, a new dimension of vibrant colours and textures embellish world’s most intuitive and legible perpetual calendar watch.

Rather than inundate the dial with windows, this perpetual calendar uses a small hand in the centre and the 12 indices to represent the month. Additionally, the date and month can be set forwards or backwards at any time, without risk to the movement.
