a factory diamond bezel

which carried with it the mystique of the deep blue sea

Patek Philippe Retrograde Perpetual Calendar bfcm24 a factory diamond bezelA perpetual calendar is like a small computer on your wrist. Think of it this way: Imagine a watch that keeps track of not only the time, but also the date, the day of the week, and the month, and also tells you whether its a leap year or not, and what the current phase of the moon is. Oh, and one more thing imagine it does all of this mechanically, using springs and gears, and that you only have to adjust it once every century or so. Crazy, right?
