So this is an easy transition from the Laurent Ferrier. As of this moment, Patek Philippe does not make a time-only tourbillon. They make them with minute repeaters and perpetual calendars and split seconds chronographs, but not on their own. And this, to me, is a crying shame. As I said above, there are people I know that would genuinely love to own a high-end toubillon, but they don’t want to look at (or pay for) the mixed salad of mega-complication watches. The 5101 as seen here, referred to as the 10 day tourbillon, was launched all the way back in 2003 and is one of the most special tourbillons in the world. (It’s essentially identical technically, by the way, to the 5100, launched by Patek in 2000, only with the addition of the tourbillon). The caliber is quite small, yet remarkably efficient, tying together two barrels to provide for ten days of power reserve. Then you have finishing and architecture that is extremely reminiscent of Patek’s record setting tourbillons of the 1950s and 60s. The entire watch, front to back, is about performance, elegance, and discretion. Look at that stepped case! What’s more, our editor-in-chief Mr. Jack Forster happens to love this watch – and if that doesn’t mean something to you, well, it should. Read the initial press release of the 5101 right here.
