The Patek Philippe
link Chronograph 5172 in white gold is a
link more recent introduction. Cara put together a lovely Introducing article during
link Baselworld (RIP) 2019 when the first example of the reference was launched. Of course, if you know your recent Patek family history, you'll recall that the 5172 replaced the 5170; both references retained the same manual-wind caliber CH 29-535 PS, a fact that's continued in today's 5172 update.
