Keks provides an initial review of Patek Philippe's 2019 new releases from Baselworld, sharing his personal thoughts on several models. He highlights pieces like the 5520P and 5212A, offering insights into their complications, aesthetics, and potential appeal to different segments of the collecting community.
I just reviewed the new releases for this year from Patek and must admit they did not disappoint this year. So many interesting and wonderful releases.... here are some of my favorites even though I like them all...

5520P / out of my budget range but super cool. Perhaps I would have wished to own this in steel 40mm as platinum 42.2mm is likely somewhat top heavy for my arms... but the complication and the execution looks superb to me. Very much look forward to handling one of these one day. Curious to hear what the alarm sounds like and feels like on the wrist...
5078G / again our of my budget range most definitely but what a dial. Looks like pure magic to my eyes. A dream piece.
5212A / a piece I can not wait to handle. Looks very intriguing. An interesting release, somewhat unexpected. I have long been a fan of the 6000G and 6006G and from an aesthetic perspective at first glance think I prefer those, however the complication on this new release is quite an interesting one I must admit... I had hoped for a simple three handed steel Calatrava with a new movement but believe we will be seeing something like that in the not too distant future.
5235R / been discussed here in some threads but it is a top elegant piece. Very classy looking and quite an interesting take on the regulateur, so different from the 5235G in this configuration. The movement is just superb. Will we see a regulateur with a jumping hour indicator in the coming years? That would be a compelling piece for me (as well I should add)...
5172G / perhaps my eyes need to get used to this one. I am a big fan of both the 5070 and 5170 series as they seem to hold so much Patek DNA. This one however makes me at first look think of a certain German manufacturer. Again, I would have to see it in the metal to form a more thorough opinion but initial impression is this one is playing it a little safe and a little far away from the manufacturers DNA.
5905R / another superb iteration of a superb reference. This dial looks just perfect. Perhaps I would have liked to see both three date windows framed, but this likely is a piece that will be quite popular. Tough pick between this and 5235R among the new releases I would think but I would likely go 5235 as it would be a better complement in my little box.
5231J / what can I say, it is gorgeous. However there is a part of me that wished they did something else with the dials for this reference. These maps are quite special but in my mind belong on the 5131 series... but perhaps I am old... or old fashioned. A fresh interpretation would have been better in my opinion, but I can not deny this is a beautiful piece nevertheless.
5168G / super cool. Naturally steel in the 5167 case would have been a better piece in my opinion, but I know that was already done on special order in the past so not going to happen. I do very much like this green however and really look forward to seeing it in the metal. I have seen the blue 5168G in the past and at the time thought it wore a bit large on my wrist for being such a thin piece. However with a matte green dial perhaps that impression changes for the better...
5726/1A / this one is quite spectacular. I realize I am not the only person to think this and considering the Nautilus frenzy going on in the world it will not be an easy piece to purchase. But this is a super elegant piece in my opinion. The blue looks a little darker and more sober than on other Nautilus dials and the whole package just looks perfect. Keeps the DNA intact. I have for a while wished to see a white dial 5990/1A but this would do as an alternative
To summarize my initial impressions, I like them all. Yes I left out the 6300G and the ladies pieces, but those I leave for another day... To pick favorites is impossible I suppose as it really comes down to ones collection and needs and budget. But there is not a piece here I would not feel happy to wear. Given my lifestyle and wearing habits the bottom two would fit the most probably, which will make my wallet happy as they are likely the hardest to acquire given the current madness around sportier references. What are your thoughts or impressions?

About the Patek Philippe Ref. 5070
The Patek Philippe reference 5070, part of the Complications collection, marked a significant return for the brand to large-format chronographs. Introduced in 1998, it was the first non-perpetual calendar chronograph produced by Patek Philippe since the reference 1463, which ceased production in the early 1960s. Its design drew inspiration from a unique Patek Philippe aviator's watch from the 1940s, characterized by its prominent case and dial layout, yet reinterpreted for a contemporary audience. This reference established a new aesthetic direction for the brand's chronographs, moving towards more substantial case dimensions.
The watch features a 42mm case, initially offered in 18k yellow gold, housing the manual-winding Caliber CH 27-70. This movement, based on a Nouvelle Lémania ébauche, was extensively finished and modified by Patek Philippe, meeting the brand's stringent quality standards. It provides a power reserve of approximately 55 hours. The dial, in this specific configuration, is black, protected by a sapphire crystal, and the watch is water-resistant to 30 meters. The fixed bezel frames the dial, and the watch is typically fitted with a leather strap.
Reference 5070 appeals to collectors interested in modern Patek Philippe chronographs that combine traditional movement architecture with a more contemporary case size. Its limited production run and the subsequent introduction of variants in other precious metals contribute to its collectibility. The reference represents a distinct period in Patek Philippe's chronograph history, bridging vintage inspirations with a new era of larger watch designs.

About the Patek Philippe Chronograph Ref. 5170
The Chronograph reference 5170, introduced in 2010, marked a significant development for Patek Philippe as it was the first serially produced chronograph to feature a fully in-house manufactured movement. This reference succeeded the reference 5070, transitioning from a Lemania-based caliber to a proprietary design, underscoring the brand's commitment to integrated manufacturing for its complications. It represents a modern interpretation of a classic chronograph layout within the Patek Philippe catalog.
The reference 5170 features a case measuring 39.4 mm in diameter and 10.9 mm in thickness, available in 18k white, rose, or yellow gold. It is equipped with the manual-winding caliber CH 29-535 PS, which offers a power reserve of 65 hours. The watch is fitted with a sapphire crystal and is water-resistant to 30 meters. The movement is visible through a sapphire case back, showcasing its intricate finishing.
This reference appeals to collectors seeking a contemporary Patek Philippe chronograph with an in-house movement. Early variants, such as the yellow gold reference 5170J-001, featured a pulsometer scale, which was later replaced by a minute track on subsequent iterations. The various metal options and dial configurations provide distinct aesthetic choices for collectors, reflecting different periods of its production run.

About the Patek Philippe Chronograph Ref. 5172
The Patek Philippe Chronograph reference 5172 represents a contemporary interpretation of the classic manually wound chronograph within the brand's collection. It succeeded the reference 5170, introducing updated case proportions and dial aesthetics while retaining the traditional two-register chronograph layout. This reference is distinguished by its round pushers and a slightly larger case diameter, offering a modern presence on the wrist while honoring Patek Philippe's heritage in complicated watchmaking. It is a key offering for collectors seeking a pure chronograph function without additional complications.
The 5172 is typically presented in a precious metal case, housing the in-house caliber CH 29-535 PS. This manual-wind movement is visible through a sapphire crystal case back, showcasing its traditional architecture and finishing. The movement provides a substantial power reserve, ensuring reliable timekeeping and chronograph operation. The front crystal is also sapphire, protecting a dial designed for legibility with applied numerals and a pulsometer scale.
This reference appeals to collectors who appreciate Patek Philippe's commitment to traditional haute horlogerie and the art of the manually wound chronograph. Its design cues, such as the syringe hands and applied Breguet numerals, evoke vintage chronographs while being executed with contemporary precision. The 5172 stands as a testament to Patek Philippe's enduring capability in producing high-quality, in-house chronograph movements, positioning it as a significant piece for enthusiasts of complicated timepieces.
