Patek Philippe Perpetual Calendar Chronograph 5270G Tray The particular Reverso we have

The particular Reverso we have here is a Classique

this pristine example comes complete with its inner box

this caliber tends to have some side effects for its name brand - in this case - other models from the era in Zeniths line up perhaps not getting the recognition that the deserve - leaving plenty of forgotten gems in the brands past

but that doesn't diminish our appreciation for this killer timepiece

Powering this masterpiece is the Lange & Söhne Caliber L901

Patek Philippe Perpetual Calendar Chronograph 5270G Tray The particular Reverso we haveA 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?
