Introducing: The Patek Philippe 5327, A Brand New Perpetual Calendar Model In A New 39mm Case (Live Pics)

This year, Patek put the focus on higher end complications, not the least of which is the perpetual calendar. We have an entirely new reference in the 5327, which is very much the same in the grand scheme of things, thought very much different in the world of Patek Philippe. The watch replaces the 5140, though the 5140 will remain in production in a black tuxedo dial and a new grey dial, both in platinum for a limited time. The 5327's story is all about the case and dial, and in some way offers a lot of what modern Patek buyers might want – a larger case and Breguet dial.

First, one must understand that the 5327 uses the very same movement that has existed with Patek perpetuals for 35+ years – caliber 240Q. So that means, technically, you'll have roughly the same movement as you'll see in the 5140 and the 3940 before that. With that comes a great micro-rotor, self-winding caliber that is quite thin, and a favorite among many purists.

The case, however, is what makes the 5327, because first and foremost it is large – 39 mm. For a Patek perpetual, this is a big deal. While I love my 3940 at 36 mm, I have no doubt there is real demand for a slightly larger QP, and 39 mm is in fact what I believe to be an ideal size.

This case is also dramatically different from those of the 5140 and 3940. It features wider lugs, with a scalloped mid case that is almost identical to the 2013 release 5227 Calatrava. The dial is brushed with Breguet numerals that fill out the would-be blank space nicely. It is available in yellow and rose gold with ivory lacquered dials on both, and in white gold with a stunning blue sunburst dial.

So again, no sweeping changes here, but the introduction of an entirely new perpetual calendar reference from Patek is no small thing in the collectible watch world – and we think the 39 mm case plus Breguet dials will please many. Pricing will be $82,784 for J, and $85,052 for G and R. You can read more here.
