At Patek Philippe, chronographs are something considered with an almost clerical serious. From the extremely complex split-seconds or perpetual calendar versions – or even both – to the most simple variation, all of them are extremely desirable. One thing to note in the actual collection is a sort of back to basics, with cleaner and more elegant watches, slightly vintage inspired – something we’ve seen with the 5370 or the 5270. Launched in 2010, with a first evolution in 2013, followed by a stronger lifting in 2015, the 5170 undergoes this year its largest cure of youth, becoming the Patek Philippe 5170R Chronograph, with 2 new references in rose gold – and one older reference being discontinued. But don’t expect a revolution. As usual, the devil is in the details.
