IWC Perpetual Calendar Chronograph

A 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 it's 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? Perpetual calendars aren't the first complication most associate with IWC, but the brand has some incredible perpetuals. This piece is one example. A Reference IW375615, this piece has utilitarian charm and high horology complication, all packaged in one beautifully executed package. 43mm in diameter and executed in stainless steel, this piece has an integrated bracelet that further situates it in the early 2000s when this model was produced. Furthermore, this watch is a chronograph, putting it in the upper echelons of grand complications.   Any old wristwatch can tell the time. Few truly define it.
