Ref. 5950A-001

May 25, 2022,19:00 PM

Introduced in 2010, the CHR 27-525 PS movement in this reference is a marvel of engineering being only 5.25 mm in height. This is all the more impressive considering it incorporates spilt seconds functionality. On top of this, it is a monopusher design with the pusher coaxial with the crown. Patek Philippe’s manual winding chronographs have always been special but this one dials it up to an eleven and to my mind, is one of the most beautiful chronographs made from any manufacturer.

The design incorporates lovely black oxidised feuille hands and applied Breguet numerals in 18k gold, raised glossy printing rendered in black lacquer, chronograph seconds divisions at 1/6 of a second to match the 3Hz beat rate of the movement, Art Deco era typography and scroll detailing at the vertices which incidentally is duplicated on the movements ring frame. Best of all, in my view, is that it has a 60-minute totaliser, not the usual 30-minute one on most chronographs. However, while there is precedent for chronograph functions to be distinguished with different coloured hands, this was not done and you have to remember that the constant seconds is on the left and the totaliser is on the right. Additionally, the no cutting of numerals and markers and the minimal text are design choices that immediately earn from me a kudos.

Finally, this watch is in stainless steel, a rarity for Patek Philippe high complications and a treat for collectors. I dare say this is a timeless reference that will be admired in any era.

My grail watch for many reasons...

 By: mdg : May 25th, 2022-19:24
...stainless steel, the fantastic case shape and slimness, the very unusual (and difficult to manufacture) complication. Great pix... Maybe one of our esteemed members will chime in with photos of his : )

If one is up for auction...

 By: mdg : May 26th, 2022-05:47 would be interesting to see the hammer price. I need to know how much of my kids' inheritance I will need to spend...

You'd merely be looking after this watch for them, so I think it makes total sense to use their inheritance for it... ;-))

PS: We don't want to go into auction prices here, but I just sent you a bunch of references via PM ;-) Cheers.

I love that.

Don't worry honey...the kids will get it all back in spades as long as I keep buying PP's !

Absolutely magnificent!

Thank's for interesting post with very nice photos.

I've read mixed responses to this watch

 By: MZHammer : May 25th, 2022-20:16
But I, for the life of me, cannot understand why. I find it one of Patek's most appealing offerings and truly a grail!

Interesting. What are the quibbles

 By: EdTonkin : May 25th, 2022-20:42
with this watch that gives rise to the mixed responses? Im curious. Thank you.

Agree strongly with Miranda. Insane piece

grail alert

 By: sierrazulu : May 25th, 2022-20:35
hope they will bring back that movement in the regular catalogue. great architecture and top-notch finishing. it's a 1/5th scale dial not matching with its 3hz, which i do find a bit odd. even their 4hz chronos are mostly 1/5th of a second, with very few ... 

An absolute grail for me and has been for a decade.

I think your description describe my feelings so closely that I’m not going to add or discuss any of what you said. Thank you immensely for these close ups. I have revisited this post several times tonight to look at the pictures. If I could pick only one... 

We are on the same page...

 By: mdg : May 25th, 2022-21:55 much as tourbillons are cool and repeaters are flashy, this one really does it for me. I am a sucker for non-round cases and stainless steel, so you can see why it's at the top of my list : )

Yep. And it think this is the ultimate execution of a modern rattrapante.

 By: ChristianDK : May 25th, 2022-22:05
The movement is so elegant and clear in its design. No modular design. No clutter. Just reduced ti it’s bare elements. The ultimate sofistication. To me it’s one of the most beautiful watch movements ever.

Superb !

My grail watch for all the reasons you have described

 By: xiu laba : May 25th, 2022-21:25
Thank you for these amazing live photos. Have never seen one in real live and doubt I would ever.

One of the great all time watches!

 By: sham1 : May 25th, 2022-22:09
I saw one today at the OAK London exhibition. A class act!

Thanks as usual for a superb presentation of a true "grail" reference --- a word that I don't like to use often, but which is totally appropriate for a steel 5950! :-)

As a Thank-You for publishing another remarkable thread and introducing our readers to this historically significant timepiece, as your senior Patek Moderator I have just "promoted" your post and cross-posted it to our Editors Picks section.....This is wh... 

Thanks again for another post on a superb reference !

 By: GLau : May 26th, 2022-02:29
The unique case, along with applied Brequet numerals and black oxidised hands, are the WOW factors. The pattern at the four corners brings it over the top IMO! Enjoy it often !

Merci, I.

Thanks, Fab. Great.

Strictly speaking, the CHR 27-525 PS draws heavy inspiration from vintage Victorin Piguet rattrapantes

 By: skyeriding : June 25th, 2022-12:26
For reference, here's a vintage Patek rattrapante, with a Victorin Piguet movement from a century ago (which is 12 ligne, or ~27mm in diameter): Next to the modern CHR 27-525 PS as found in the 5950 (which is also 27.3 mm in size): There are many similari...  

Am speechless! Magnifique!

Spectacular watch

 By: jmpTT : May 27th, 2022-03:06
Such an exceptional movement, I think this remains easily the most impressive split seconds chronograph movement made today, though Vacheron has a similar movement. This would be a capstone watch to any collection, also one that could be worn and enjoyed....

a dream watch... thanks for sharing these wonderful photographs! Hope to one day handle one physically, until then these photos will have to do!
