The case of this Heritage Perpetual Calendar measures 42mm in diameter and is made of 18k white gold. The dial is made of Grand Feu enamel with a typically Moser fumé blue colour – with a slight dégradé effect. The display is clear and elegant, with crisp white Roman numerals and railroad tracks, as well as thin polished swallow-tail hands. In addition to the central hours/minutes, there is a small seconds at 6 o’clock, a discreet power reserve at 9 o’clock and a large date at 3 o’clock.
