The sportier Moser — water resistant, more robust, still usually wearing the fumé dial with no branding. The interchangeable strap and the screw-down crown are the practical differences from the Endeavour; the perpetual calendar Moser puts in both is the same one, which indicates the month by a short central hand pointing at an hour marker rather than through a window.
