Neuhausen am Rheinfall, July 7th, 2015

H. Moser & Cie. joins the fight against Duchenne Muscular Dystrophy by participating in the Only Watch Charity Auction organized by the Monegasque Association against Muscular Dystrophy. For the occasion, the Manufacture has created a unique piece, the Endeavour Perpetual Calendar Only Watch, revisiting the flagship model in its collection in a highly symbolic execution.

On November 7th, 2015, Geneva will host the 6th edition of the Only Watch Charity Auction with proceeds donated for research on Duchenne Muscular Dystrophy. H. Moser & Cie. joins the action with the donation of a unique piece, the Endeavour Perpetual Calendar Only Watch. This exceptional watch is not only remarkable for its complexity but also for the symbolic value and the message it conveys. In honour of the young victims of Duchenne Muscular Dystrophy, for whom every movement is an accomplishment and each day is a challenge, the children of H. Moser & Cie. employees have handwritten the design for the perpetual calendar dates. As a symbol of the fundamental principle of life, with its strength and radiance, the red small seconds hand in the Endeavour Perpetual Calendar Only Watch provides a stark contrast to the signature fumé dial, while the red strap lining also takes up this colour, with a discreet and modern effect.


For the case of the Endeavour Perpetual Calendar Only Watch, the watchmakers at H. Moser & Cie. chose titanium with a DLC finish. Durable, lightweight, hypoallergenic, the polished titanium accents the sleek contemporary design of this model, adding a timeless dimension. Revealed through the crystal case-back, is the HMC 341 movement with a minimum 7-days power reserve. In addition, the Moser interchangeable escapement has been fitted with an Original Straumann Double-Hairspring®, a very rare feature in honour of this exceptional charity event.


This watch will be on display during a tour of the collection in Monaco at the Monaco Yacht Show, September 23rd  to 26th, 2015, and will be followed by stops in Hong Kong, Beijing, New York, London, and finishing in Geneva from November 5th to 7th, 2015.


A perpetual calendar in the service of eternal hope: a complication was never so aptly named.
