'Named after Heinrich Moser's first wife Charlotte Mayu, the Mayu collection showcases H. Moser's eye for colour and design, with a range of cases made in different kinds of gold. Boasting a 38.8 millimeter case, the watch has incredible presence on the wrist. Yet, the most striking aspect of the watch is the blue fumé dial, which is confirmed by the Certificate of Authenticity as being a unique edition from the Mayu collection named "The Mayu Dark Blue Fumé". It is a limited to 1 piece only and a prototype wristwatch.'
