H. Moser & Cie.

Endeavour Perpetual Calendar Most perpetual calendars crowd the dial with subdials. Moser's shows the date in a window at three o'clock and the month with a small arrow-shaped hand at the centre, pointing at the twelve hour markers, one for each month, so the dial stays almost as calm as a time-only watch. Its perpetual calendar took a prize at the Grand Prix d'Horlogerie de Genève in 2006, and it remains the clearest example of this small house's habit of hiding real difficulty behind restraint. A good choice for readers who think complications have to look complicated.
