For the Only Watch 2015 charity auction, to help raise money to benefit research for Duchenne Muscular Dystrophy, H. Moser & Cie has produced a one-of-a-kind version of their Endeavour Perpetual Calendar. This special piece comes in a 40.8 mm diameter titanium case with a DLC finish.

Interestingly, H. Moser & Cie asked the children of employees at the company to handwrite the design for the perpetual calendar’s date indication, in honor of the young victims of Duchenne Muscular Dystrophy. Also, to contrast the sunburst fumé dial, the small second hand at 6 o’clock is accented in red with a black hand-stitched alligator strap lined in red leather to match.
