One of the coolest and most complicated Panerai’s is one you don’t often hear much about.   The Luminor 1950 Equation of Time Tourbillon Titanio, otherwise known as L’Astronomo, doesn’t even look like all that much if you just stare at the dial, but believe us, it’s got the goods.

In fact, beyond the the time, date, and power reserve, it also features sunrise and sunset, equation of time, a star disk on the back, oh and a tourbillon.  Yes, ALL that.

L’Astronomo is 50mm in diameter, which is larger than most watches we’d normally recommend, but considering just how complicated this watch is and the fact that the case is titanium, we’ll let that slide. 

Only 30 of these special PAMs will be made and each client may choose exact coordinates for which the sunrise, sunset, and equation of time complications may be customized.  The depiction of the night sky, viewable from the case back, will also match the owner’s designated coordinates. 

Sitting above the map of the night’s sky on the caseback is the in-house 30 second tourbillon.  The manually wound movement has a power reserve of four days and is comprised of 375 parts.
